Currently the Grid depends on there being a root level "portal" div in your HTML. Insert this snippet as the last child of your <body> tag:
<div id="portal" style="position: fixed; left: 0; top: 0; z-index: 9999;" />Once you've got that done, the easiest way to use the Data Grid is to give it a fixed size:
<DataEditor width={500} height={300} {...props} />The Grid will never change any of your underlying data. You have to do so yourself when one of the callbacks is invoked. For example, when the user edits the value in a cell, the Grid will invoke the onCellEdited callback. If you don't implement that callback, or if it doesn't change the undelying data to the new value, the Grid will keep displaying the old value.
Note that there is currently no way to tell the grid that data has changed. It has to be forced to redraw by passing a different object to the getCellContent property. This triggers the entire grid to redraw. You should avoid changing the getCellContent object ID as much as possible otherwise.
If you want to use the default Image overlay preview you must remember to include the react-responsive-carousel css file or it will not function correctly. This should be available in your node-modules.
import "react-responsive-carousel/lib/styles/carousel.min.css";Grid always passes col/row coordinate pairs in the format [col, row] and never [row, col]. This is to more accurately match an [x, y] world, even though most english speakers will tend to say "row col".
Details of each property can be found by clicking on it.

Grid columns are the basic horizontal building block of the data grid. At their most basic level a GridColumn is just an object which contains a title and a width or id. Their type looks like:
interface BaseGridColumn {
readonly title: string;
readonly group?: string;
readonly icon?: GridColumnIcon | string;
readonly overlayIcon?: GridColumnIcon | string;
readonly hasMenu?: boolean;
readonly style?: "normal" | "highlight";
readonly themeOverride?: Partial<Theme>;
readonly trailingRowOptions?: {
readonly hint?: string;
readonly addIcon?: string;
readonly targetColumn?: number | GridColumn;
};
}
interface SizedGridColumn extends BaseGridColumn {
readonly width: number;
readonly id?: string;
}
interface AutoGridColumn extends BaseGridColumn {
readonly id: string;
}
export type GridColumn = SizedGridColumn | AutoGridColumn;| Property | Description |
|---|---|
| title | The title of the column |
| group | The name of the group the column belongs to |
| icon | The icon the column belongs to. The icon must be either one of the predefined icons or an icon passed to the headerIcons prop |
| overlayIcon | An icon which is painted on top offset bottom right of the icon. Must be a predefined icon or an icon passed to the headerIcons prop |
| hasMenu | Enables/disables the menu dropdown indicator. If not enabled, onHeaderMenuClick will not be emitted. |
| style | Makes the column use the highlighted theming from the Theme. themeOverride can be used to perform the same effect. |
| themeOverride | A Partial<Theme> which can be used to override the theming of the header as well as all cells within the column. |
| trailingRowOptions | Overrides the DataEditor level prop for trailingRowOptions for this column |
GridCell is the basic content building block of a data grid. There are many types of cells available out of the box and more available in additional packages.
| Cell Kind | Description |
|---|---|
| Uri | Displays uris. Can be edited. |
| Text | Displays arbitrary text. |
| Image | Displays one or more images. |
| RowID | Designed to show primary keys in data sources. |
| Number | Displays numbers with formatting options and better editing support. |
| Bubble | Displays lists of data in little bubbles. |
| Boolean | Displays a checkbox which can be directly edited if desired. |
| Loading | Useful for when data is loading. Rendering is basically free. |
| Markdown | Displays markdown when opened. |
| Drilldown | Similar to a bubble cell, but allows embedding text and images with each cell. |
| Protected | Displays stars instead of data. Useful for indicating that hidden data is present but unavailable to the user. |
| Custom | Has no rendering by default and must be provided via drawCell. Used to implement 3rd party cells. |
GridSelection is the most basic representation of the selected cells, rows, and columns in the data grid. The current property accounts for the selected cell and the range of cells selected as well. It is the selection which is modified by keyboard and mouse interaction when clicking on the cells themselves.
The rows and columns properties both account for the columns or rows which have been explicitly selected by the user. Selecting a range which encompases the entire set of cells within a column/row does not implicitly set it into this part of the collection. This allows for distinguishing between cases when the user wishes to delete all contents of a row/column and delete the row/column itself.
interface GridSelection {
readonly current?: {
readonly cell: Item;
readonly range: Readonly<Rectangle>;
readonly rangeStack: readonly Readonly<Rectangle>[];
};
readonly columns: CompactSelection;
readonly rows: CompactSelection;
}The cell is the [col, row] formatted cell which will have the focus ring drawn around it. The range should always include the cell and represents additional cells which can be edited via copy, delete and other events. The range may or may not include partial spans depending on the spanRangeBehavior set.
The data grid uses the Theme provided by the styled-components ThemeProvider. This is used to style editors as well as the grid itself. The theme interface is flat. The data grid comes with a built in theme which it will use to fill in any missing values.
| Property | Type | Description |
|---|---|---|
| accentColor | string | The primary accent color of the grid. This will show up in focus rings and selected rows/headers. |
| accentFg | string | A foreground color which works well on top of the accent color. |
| accentLight | string | A lighter version of the accent color used to hint selection. |
| textDark | string | The standard text color. |
| textMedium | string | A lighter text color used for non-editable data in some cases. |
| textLight | string | An even lighter text color |
| textBubble | string | The text color used in bubbles |
| bgIconHeader | string | The background color for header icons |
| fgIconHeader | string | The foreground color for header icons |
| textHeader | string | The header text color |
| textGroupHeader | string | undefined | The group header text color, if none provided the textHeader is used instead. |
| textHeaderSelected | string | The text color used for selected headers |
| bgCell | string | The primary background color of the data grid. |
| bgCellMedium | string | Used for disabled or otherwise off colored cells. |
| bgHeader | string | The header background color |
| bgHeaderHasFocus | string | The header background color when its column contains the selected cell |
| bgHeaderHovered | string | The header background color when it is hovered |
| bgBubble | string | The background color used in bubbles |
| bgBubbleSelected | string | The background color used in bubbles when the cell is selected |
| bgSearchResult | string | The background color used for cells which match the search string |
| borderColor | string | The color of all vertical borders and horizontal borders if a horizontal override is not provided |
| horizontalBorderColor | string | undefined | The horizontal border color override |
| drilldownBorder | string | The ring color of a drilldown cell |
| linkColor | string | What color to render links |
| cellHorizontalPadding | number | The internal horizontal padding size of a cell. |
| cellVerticalPadding | number | The internal vertical padding size of a cell. |
| headerFontStyle | string | The font style of the header. e.g. bold 15px |
| baseFontStyle | string | The font style used for cells by default, e.g. 13px |
| fontFamily | string | The font family used by the data grid. |
| editorFontSize | string | The font size used by overlay editors. |
Example usage:
dataGridRef.current.updateCells([{ cell: [10, 10] }, { cell: [11, 10] }, { cell: [12, 10] }]);Causes the data grid to rerender these specific cells. Rerendering a single cell is significantly faster than invalidating the getCellContent callback as in the latter case all cells must be redrawn.
getBounds: (col: number, row?: number) => Rectangle | undefined;getBounds returns the current bounding box of a cell. This does not need to be a currently rendered cell.
scrollTo: (
col: number,
row: number,
dir?: "horizontal" | "vertical" | "both",
paddingX?: number,
paddingY?: number
) => void;Requests the data grid to scroll to a particular location. If only one direction is requested it will get as close as it can without scrolling the off axis. Padding can be applied to inset the cell by a certain amount.
columns: readonly GridColumn[];columns is an array of objects of type GridColumn describing the column headers. The length of the array is the number of columns to display.
rows: number;rows is the number of rows to display.
getCellContent: (cell: Item) => GridCell;getCellContent returns an object of type GridCell describing the contents for the cell at the given coordinates.
freezeColumns?: number;Set to a positive number to freeze columns on the left side of the grid during horizontal scrolling.
type CellArray = readonly (readonly GridCell[])[];
type GetCellsThunk = () => Promise<CellArray>;
getCellsForSelection?: true | (selection: Rectangle) => CellArray | GetCellsThunk;getCellsForSelection is called when the user copies a selection to the clipboard or the data editor needs to inspect data which may be outside the curently visible range. It must return a two-dimensional array (an array of rows, where each row is an array of cells) of the cells in the selection's rectangle. Note that the rectangle can include cells that are not currently visible.
If true is passed instead of a callback, the data grid will internally use the getCellContent callback to provide a basic implementation of getCellsForSelection. This can make it easier to light up more data grid functionality, but may have negative side effects if your data source is not able to handle being queried for data outside the normal window.
If getCellsForSelection returns a thunk, the data may be loaded asynchronously, however the data grid may be unable to properly react to column spans when performing range selections. Copying large amounts of data out of the grid will depend on the performance of the thunk as well.
markdownDivCreateNode?: (content: string) => DocumentFragment;If markdownDivCreateNode is specified, then it will be used to render Markdown, instead of the default Markdown renderer used by the Grid. You'll want to use this if you need to process your Markdown for security purposes, or if you want to use a renderer with different Markdown features.
onVisibleRegionChanged?: (range: Rectangle) => void;onVisibleRegionChanged is called whenever the visible region changed. The new visible region is passed as a Rectangle.
interface EditorProps {
readonly onChange: (newValue: GridCell) => void;
readonly onFinishedEditing: (newValue?: GridCell) => void;
readonly isHighlighted: boolean;
readonly value: GridCell;
}
type ProvideEditorCallback = (cell: GridCell) =>
(React.FunctionComponent<EditorProps> & {
disablePadding?: boolean;
disableStyling?: boolean;
})
| undefined;
provideEditor?: ProvideEditorCallback<GridCell>;When provided the provideEditor callbacks job is to be a constructor for functional components which have the correct properties to be used by the data grid as an editor. The editor must implement onChange and onFinishEditing callbacks as well support the isHighlighted flag which tells the editor to begin with any editable text pre-selected so typing will immediately begin to overwrite it.
rowHeight: number | ((index: number) => number);rowHeight is the height of a row in the table. It defaults to 34. By passing a function instead of a number you can give different heights to each row. The index is the zero-based absolute row index.
rowMarkers?: "checkbox" | "number" | "both" | "none";rowMarkers determines whether to display the marker column on the very left. It defaults to none. Note that this column doesn't count as a table column, i.e. it has no index, and doesn't change column indexes.
smoothScrollX?: boolean;
smoothScrollY?: boolean;Controls smooth scrolling in the data grid. Defaults to false. If smooth scrolling is not enabled the grid will alaways be cell aligned in the non-smooth scrolling axis.
showSearch?: boolean;showSearch causes the search box built into the data grid to become visible. The data grid does not provide an in-built way to show the search box, so it is suggested to hook into the ctrl/cmd+f accelerator or add a button to your apps chrome.
onSearchClose?: () => void;If onSearchClose is not provided and showSearch is set to true, the search box will be shown but there will be no close button. Providing an onSearchClose callback enables the close button and the event will emit when it is clicked.
drawCell?: (args: {
ctx: CanvasRenderingContext2D;
cell: GridCell;
theme: Theme;
rect: Rectangle;
hoverAmount: number;
hoverX: number | undefined;
hoverY: number | undefined;
highlighted: boolean;
imageLoader: ImageWindowLoader;
}) => boolean;You can specify drawCell to enable rendering your own cells. The Grid will call this for every cell it needs to render. It should either render the cell and return true, or not render anything and return false, in which case the Grid will render the cell.
drawHeader?: (args: {
ctx: CanvasRenderingContext2D;
column: GridColumn;
theme: Theme;
rect: Rectangle;
hoverAmount: number;
isSelected: boolean;
isHovered: boolean;
hasSelectedCell: boolean;
spriteManager: SpriteManager;
menuBounds: Rectangle;
}) => boolean;drawHeader may be specified to override the rendering of a header. The grid will call this for every header it needs to render. Header rendering is not as well optimized because they do not redraw as often, but very heavy drawing methods can negatively impact horizontal scrolling performance. The return result works the same way as drawCell, false means the default rendering will happen and true means the default rendering will not happen.
It is possible to return false after rendering just a background and the regular foreground rendering will happen.
getGroupDetails?: (groupName: string) => ({
name: string;
icon?: string;
overrideTheme?: Partial<Theme>;
actions?: {
title: string;
onClick: (e: GridMouseGroupHeaderEventArgs) => void;
icon: GridColumnIcon | string;
}[];
});getGroupDetails is invoked whenever a group header is rendered. The group details are used to provide a name override for the group as well as an icon, a list of actions which can be activated by the user, and an overrideTheme which will impact the rendering of all child cells of the group and all column headers in the group.
getRowThemeOverride?: (row: number) => Partial<Theme> | undefined;Whenever a row is rendered the row theme override is fetched if provided. This function should aim to be extremely fast as it may be invoked many times per render. All cells in the row have this theme merged into their theme prior to rendering.
groupHeaderHeight?: number;The height of the group headers in the data grid. If not provided this will default to the headerHeight value.
headerHeight: number;headerHeight is the height of the table header. It defaults to 36.
headerIcons?: Record<string, (spriteProps: { fgColor: string, bgColor: string }) => string>;Providing custom header icons to the data grid must be done with a somewhat non-standard mechanism to allow theming and scaling. The headerIcons property takes a dictionary which maps icon names to functions which can take a foreground and background color and returns back a string representation of an svg. The svg should contain a header similar to this <svg width="20" height="20" fill="none" xmlns="http://www.w3.org/2000/svg"> and interpolate the fg/bg colors into the string.
We recognize this process is not fantastic from a graphics workflow standpoint, improvements are very welcome here.
overscrollX?: number;
overscrollY?: number;The overscroll properties are used to allow the grid to scroll past the logical end of the content by a fixed number of pixels. This is useful particularly on the X axis if you allow for resizing columns as it can make resizing the final column significantly easier.
rightElementSticky?: boolean;
rightElement?: React.ReactNode;The right element is a DOM node which can be inserted at the end of the horizontal scroll region. This can be used to create a right handle panel, make a big add button, or display messages. If rightElementSticky is set to true the right element will be visible at all times, otherwise the user will need to scroll to the end to reveal it.
rowMarkerWidth?: number;rowMarkerWidth is the width of the marker column on the very left. By default, it adapts based on the number of rows in your data set.
verticalBorder?: ((col: number) => boolean) | boolean;Controls the drawing of the left hand vertical border of a column. If set to a boolean value it controls all borders. Defaults to true.
gridSelection?: GridSelection;
onGridSelectionChange?: (newSelection: GridSelection | undefined) => void;The currently selected cell and range in the data grid. If provided the onGridSelectionChange event should also be used as this property is controlled via that event. If this property is not provided, nor should the onGridSelectionChange event be.
spanRangeBehavior?: "default" | "allowPartial";If set to default the gridSelection will always be expanded to fully include any spans within it. This means in some cases the range of the selection may be inflated to the size of the entire sheet, however the user will be unable to highlight partial spans.
If allowPartial is set no inflation behavior will be enforced.
onSelectionCleared?: () => void;Emitted when the current selection is cleared, usually when the user presses "Escape". rowSelection, columnSelection, and gridSelection should all be empty when this event is emitted. This event only emits when the user explicitly attempts to clear the selection.
rangeSelect?: "none" | "cell" | "rect" | "multi-cell" | "multi-rect"; // default rect
columnSelect?: "none" | "single" | "multi"; // default multi
rowSelect?: "none" | "single" | "multi"; // default multiControls if multi-selection is allowed. If disabled, shift/ctrl/command clicking will work as if no modifiers are pressed.
When range select is set to cell, only one cell may be selected at a time. When set to rect one one rect at a time. The multi variants allow for multiples of the rect or cell to be selected.
rangeSelectionBlending?: "exclusive" | "mixed"; // default exclusive
columnSelectionBlending?: "exclusive" | "mixed"; // default exclusive
rowSelectionBlending?: "exclusive" | "mixed"; // default exclusiveControls which types of selections can exist at the same time in the grid. If selection blending is set to exclusive, the grid will clear other types of selections when the exclusive selection is made. By default row, column, and range selections are exclusive.
interface Highlight {
readonly color: string;
readonly range: Rectangle;
}
highlightRegions?: readonly Highlight[];Highlight regions are regions on the grid which get drawn with a background color and a dashed line around the region. The color string must be css parseable and the opacity will be removed for the drawing of the dashed line. Opacity should be used to allow overlapping selections to properly blend in background colors.
fillHandle?: boolean;Controls the visibility of the fill handle used for filling cells with the mouse.
onDelete?: (selection: GridSelection) => GridSelection | boolean;onDelete is called when the user deletes one or more rows. gridSelection is current selection. If the callback returns false, deletion will not happen. If it returns true, all cells inside all selected rows, columns and ranges will be deleted. If the callback returns a GridSelection, the newly returned selection will be deleted instead.
imageEditorOverride?: ImageEditorType;If imageEditorOverride is specified, then it will be used instead of the default image editor overlay, which is what the user sees when they double-click on an image cell.
onCellEdited?: (cell: Item, newValue: EditableGridCell) => void;onCellEdited is called when the user finishes editing a cell. Note that you are responsible for setting the new value of the cell.
onDeleteRows?: (rows: readonly number[]) => void;onDeleteRows is called when the user deletes one or more rows. rows is an array with the absolute indexes of the deletes rows. Note that it is on you to actually effect the deletion of those rows.
onFinishedEditing?: (newValue: GridCell | undefined, movement: Item) => void;Emitted whenever the data grid exits edit mode. The movement indicates which direction the user requested the selection move towards. -1 is left/up, 1 is right/down.
onGroupHeaderRenamed?: (groupName: string, newVal: string) => voidIf provided group headers will have an icon allowing users to rename them. When a user renames a group header this event will be emitted. It is up to the developer to actually rename the header.
onPaste?: ((target: Item, values: readonly (readonly string[])[]) => boolean) | boolean;onPaste is called when data is pasted into the grid. If left undefined, the DataEditor will operate in a fallback mode and attempt to paste the text buffer into the current cell assuming the current cell is not readonly and can accept the data type. If onPaste is set to false or the function returns false, the grid will simply ignore paste. If onPaste evaluates to true the grid will attempt to split the data by tabs and newlines and paste into available cells.
The grid will not attempt to add additional rows if more data is pasted then can fit. In that case it is advisable to simply return false from onPaste and handle the paste manually.
trailingRowOptions?: {
readonly tint?: boolean;
readonly hint?: string;
readonly sticky?: boolean;
}
onRowAppended?: () => void;onRowAppended controls adding new rows at the bottom of the Grid. If onRowAppended is defined, an empty row will display at the bottom. When the user clicks on one of its cells, onRowAppended is called, which is responsible for appending the new row. The appearance of the blank row can be configured using trailingRowOptions.
maxColumnWidth?: number;
minColumnWidth?: number;If maxColumnWidth is set with a value greater than 50, then columns will have a maximum size of that many pixels.
If the value is less than 50, it will be increased to 50. If it isn't set, the default value will be 500.
onCellClicked?: (cell: Item) => void;onCellClicked is called whenever the user clicks a cell in the grid.
onCellActivated?: (cell: Item) => void;onCellActivated is called whenever the user double clicks, taps Enter, or taps Space on a cell in the grid.
onColumnMoved?: (startIndex: number, endIndex: number) => void;onColumnMoved is called when the user finishes moving a column. startIndex is the index of the column that was moved, and endIndex is the index at which it should end up. Note that you have to effect the move of the column, and pass the reordered columns back in the columns property.
onColumnResized?: (column: GridColumn, newSize: number) => void;onColumnResized is called when the user finishes resizing a column. newSize is the new size of the column. Note that you have change the size of the column in the GridColumn and pass it back to the grid in the columns property.
onGroupHeaderClicked?: (colIndex: number, event: GroupHeaderClickedEventArgs) => void;Emitted whenever a group header is clicked.
onGroupHeaderContextMenu?: (colIndex: number, event: GroupHeaderClickedEventArgs) => voidEmitted whenever a group header's context menu should be presented, usually right click.
onHeaderClicked?: (colIndex: number, event: HeaderClickedEventArgs) => void;Emitted whenever a header is clicked.
onHeaderContextMenu?: (colIndex: number, event: HeaderClickedEventArgs) => void;Emitted whenever a column header's context menu should be presented, usually right click.
onHeaderMenuClick?: (col: number, screenPosition: Rectangle) => void;onHeaderMenuClick is called when the user clicks the menu button on a column header. col is the column index, and screenPosition is the bounds of the column header. You are responsible for drawing and handling the menu.
onItemHovered?: (args: GridMouseEventArgs) => void;onItemHovered is called when the user hovers over a cell, a header, or outside the grid.
onMouseMove?: (args: GridMouseEventArgs) => void;Emitted any time the mouse moves. Most behaviors relying on this should be debounced for performance reasons.
onRowMoved?: (startIndex: number, endIndex: number) => void;Called whenever a row re-order operation is completed. Setting the callback enables re-ordering by dragging the first column of a row.
preventDiagonalScrolling?: booling;Set to true to prevent any diagonal scrolling.
rowSelectionMode?: "auto" | "multi";rowSelectionMode changes how selecting a row marker behaves. In auto mode it adapts to touch or mouse environments automatically, in multi-mode it always acts as if the multi key (Ctrl) is pressed.
showMinimap?: boolean;Enables/disables the interactive minimap. Default to false.
scrollToEnd?: boolean;When this property changes to true, the Grid will scroll all the way to the right. Glide uses that when the user clicks the "Add Column" button.
isDraggable?: boolean;
onDragStart?: (args: GridDragEventArgs) => void;If isDraggable is set, the whole Grid is draggable, and onDragStart will be called when dragging starts. You can use this to build a UI where the user can drag the Grid around.
Behavior not defined or officially supported. Feel free to check out what this does in github but anything in here is up for grabs to be changed at any time.
