The search results did not directly point to the specific code responsible for the triangle sign's positioning in the DatePicker component. However, based on the issue description and the typical structure of Ant Design components, the problem might be related to the CSS styling of the DatePicker component.

Let's propose a potential fix by adjusting the CSS to ensure the triangle sign is correctly positioned. We can add a CSS rule to handle the flex-end layout scenario.

Here is a proposed CSS modification:

/* Add this CSS rule to ensure the triangle sign is correctly positioned */
.ant-picker-dropdown {
  .ant-picker-range-arrow {
    right: auto;
    left: 50%;
    transform: translateX(-50%);
  }
}

This CSS rule targets the dropdown of the DatePicker component and ensures that the triangle sign is centered horizontally when the DatePicker is used in a flex-end layout.

Please add this CSS rule to your project's stylesheet and see if it resolves the issue. If the problem persists, further investigation into the component's implementation might be necessary.

For further assistance, please describe your question in the comments and @petercat-assistant to start a conversation with me.

主要是这处的问题，trrigger自己改了popupAligin为tr，但是外面没有收到，依旧是以tl来判断offsetUnit，所以展示出了问题 明天继续看看
