RowGroup and ScrollY

Wooly65

I decided to use RowGroup for the first time and am have issues with column sizing when I use ScrollY.
Using BootStrap5 showing in Chrome.

I have commented out ScrollY, so uncomment it to see the issue.

The last comment in the discussion below also comments about ScrollY

Unfortunately yes. There is something "weird" in the browsers when the first row in the table body has a colspan cell. I do not yet have a fix for this as I don't yet fully understand what is happening in the browsers, nor how to counteract it.

I have the exact same problem.

I used the solution from this post and it has worked for me.
