Can Table be virtualized in just the vertical direction?

[abeljohn]

I'm trying to add virtualization to a Table that has inconsistent row heights due to cells with text wrap. When all the columns are in view, the virtualization works as well as it could by using estimatedRowHeight. But when the Table also has horizontal scroll, if the tallest cell in a given row is not initially in view, then the row height jumps around a bit when that column is scrolled into view. I have made an example here: https://codesandbox.io/p/sandbox/tyd6mz

Since my Table has a fixed number of columns and many rows, most of the performance benefit comes from the vertical virtualization. I tried a custom TableLayout implementation that marks every column as "sticky", but it didn't work quite the way I expected it to. Is there a good way to disable the horizontal virtualization on Table? Or would it be possible to achieve this with a custom Virtualizer implementation?

I've come up with a custom TableLayout that manages to disable the horizontal virtualization by modifying buildRow and addVisibleLayoutInfos: https://codesandbox.io/p/devbox/delicate-wave-forked-ln48c2

Unfortunately since setChildHeights and addVisibleLayoutInfos are marked as private in the @react-stately/layout class, I ended up copy-pasting the entire implementation rather than extending the exported class.

Thanks for sharing, I think this is fine for now, but we can keep it under consideration as something to make easier in the future.
