MUI appears to be more mature but DataSheetGrid has spreadsheet-like range selection out of the box while MUI only provides a beta version under its premium plan.

From MUI: "This feature is not stable yet, meaning that its APIs may suffer breaking changes. While in development, all props and methods related to cell selection must be prefixed with unstable".

This feature tends to be pro or unavailable across options I've seen so it is great that DataSheetGrid has rolled out a working implementation.

Edit: Changed 'its pro plan' to 'its premium plan'.

One difference I can see is that this has spreadsheet-like range selection which is important for some apps.

@nick-keller, thanks for making this. I came across it a month ago and it looks very promising. It has range selection out of the box (a pro feature in some alternative solutions) and you can customize cells. However, the best example of what one could create with this is shown as a screenshot in the 'customizable' section of the landing page but there is no demo showing that this is actually possible. I think I struggled to create custom headers and header menus with this so I moved to AG-Grid and implemented my own range selection.

Thanks, maybe I should implement more examples, it looks like this is the most efficient way to help people.
