Column selector in tables should be scrollable, for entity with 48+ columns you are not able to select columns to hide/unhide.
Thank you for reporting the problem. We have created a YouTrack issue, see the link on the right. Now I suggest using the DataGrid component. Its column visibility menu has no such problems.
Thank you for creating issue, I will try out your suggestion.
Have a great day!
