Is it possible to access the row virtualizer instance?

[mihaio100]

I have a table with virtualization enabled and I've been trying to figure out how to use the scrollToIndex function provided by react-virtual (as per docs). However I can't seem to figure out how to get the Virtualizer instance in order to access that function, or whether this is even possible at all at the moment?

Looking through the source code, it looks like a rowVirtualizer instance is created inside MRT_TableBody but isn't being exposed in any way, so would there be a way for me to use scrollToIndex through MRTable?

Edit: There is now a virutalizerInstanceRef prop. It can be seen used in the infinite scrolling example

So there is currently no reference to the virtualizer currently, though I could probably expose a ref to it.

If all you are wanting to do is scroll to the top, you could do that with the muiTableContainerProps ref.

Something like this

  const tableContainerRef = useRef(null);

  //scroll to top of table when sorting or filters change
  useEffect(() => {
    if (tableContainerRef.current) {
      tableContainerRef.current.scrollTop = 0;
    }
  }, [sorting, columnFilters, globalFilter]);

...
<MaterialReactTable
  muiTableContainerProps={{
    ref: tableContainerRef
  }}
/>

But adding a virtualizerRef to the library itself is probably a good idea and not too dangerous. I'll see if that works and maybe add it soon.

Thank you for clarifying!

So actually, check out the latest version and the infinite scrolling example on the docs site. I added a virtualizerInstanceRef prop

Thanks so much for this! We were just getting ready to Fork & create a PR so we appreciate the < 24h turnaround.
