AnalyticalTable: Scrolling and virutalization

[sebastian-kraemer]

As mentioned in #6615, we are having issues with sluggish scrolling. As there seems to be no progress, I'm wondering if there is a possibility to improve this somehow differently.

We are only displaying 100 rows and for that we don't need virtualization. If I show 100 rows via the visibleRows attribute, the performance is way better. But unfortunately, the header row is also scrolled. Is there a way to keep the header row visible on top while displaying a fixed row count?

Hi @sebastian-kraemer

The linked issue is mainly regarding scrolling via scrollbar, scrolling via mouse-wheel, trackpad, touch, etc. should be fine, especially for 100 rows (if they are not heavily loaded with custom content).
Could you share your implementation so we can take a look?

You can disable both vertical and horizontal virtualization by setting the respective "overscan" prop (overscanCount /
overscanCountHorizontal) to a very high number.
