Textbreak (tb) makes Sheet very laggy - Performance Issues Bug

[Erivess]

Im encountering significant performance issues when using fortunesheet to render Excel files that have around 40 or more rows and 3-4 containing a lot of text. The spreadsheet becomes quite laggy and impossible to work on. We do not use any editing operations and just use fortunesheet to "view" the excel file.

I'm wondering if there's a way to optimize fortunesheet for better performance with larger datasets - even tho I would not consider 40 rows a "large dataset".

Does fortunesheet support virtualization or any performance enhancements for big data sets?

Happy for any help.

that should not be happening, i have used this package for sheets with 10k+ rows. you might want to relook at your implementation.

Hi @Erivess! Do your cells data have line breaks? If so, it may be linked to #578.
If not, check for accidental re-renders in your implementation.

@Corbe30 @sanchit3008 Yes, we already identified the issue: We defined tb for every single cell and that caused the lag. After removing it from every cell, the lag disappeared.

Hi @Erivess, we have fixed the performance issue with tb in the new release v0.19.18! Let me know if you're still facing the issue.
