Good day!
I've been having this problem for a while now, in some parts of my report the columns overlap, no matter what I do on the styling I still can't fix it. Here's how it looks:
This is a table without borders on both the table and the textboxes.
While this one is a table with borders but no borders on the textboxes.
I'd also like to add that this issue is inconsistent. This mostly happens when opening the report on Google Chrome but it doesnt happen on Edge. Also there are zoom levels that the layout is fixed for example if I zoom about 150% the layout gets fixed.
Also I think what's strange is that only the colored columns overlaps. As you can see the columns with just white background are working well.
