Does it work with screen readers and other a11y tools?
Yes. Unfortunately none of the primary developers are accessibility users so there are likely flaws in the implementation we are not aware of. Bug reports welcome!
Does it support my data source?
Data Grid is agnostic about the way you load/store/generate/mutate your data. What it requires is that you tell it which columns you have, how many rows, and to give it a function it can call to get the data for a cell in a specific row and column.
Does it do sorting, searching, and filtering?
Search is included. You provide the trigger, we do the search. Example in our storybook.
Filtering and sorting are something you would have to implement with your data source. There are hooks for adding column header menus if you want that.
The reason we don't add filtering/sorting in by default is that these are usually very application-specific, and can often also be implemented more efficiently in the data source, via a database query, for example.
Can it do frozen columns?
Can I render my own cells?
Yes, but the renderer has to use HTML Canvas. Simple example in our Storybook.
Why does Data Grid use HTML Canvas?
Originally we had implemented our Grid using virtualized rendering. We virtualized both in the horizontal and vertical direction using react-virtualized. The problem is simply scrolling performance. Once you need to load/unload hundreds of DOM elements per frame nothing can save you.
There are some hacks you can do like setting timers and entering into a "low fidelity" rendering mode where you only render a single element per cell. This works okay until you want to show hundreds of cells and you are right back to choppy scrolling. It also doesn't really look or feel great.
I want to use this with Next.js / Vercel, but I'm getting weird errors
The easiest way to use the grid with Next is to create a component which wraps up your grid and then import it as a dynamic.
