That’s not quite true. The issue is, the browser has a lot of work to do to render the changes in the data in the table column. Katalon doesn’t know how long that will take, so YOU need to teach it how to do that. As you’ve already guessed, you do that with various “waits”.
It would help us if you showed us your code and what you’ve tried that didn’t work.
So it was executing but not doing what you would expect. Again, we can’t guess what’s wrong, we need to see the code (and errors if you have them).
