I have a datatable with various columns, including one that could potentially include 4k char output. I currently set up the columns to display 200px worth of text. If they want to see the rest of it, they just hover over it and a pop-up appears.
This works fine, except when users are close to the right-side or bottom of the window. The pop-up extends from the cursor down and to the right, so the pop-up causes issues with scrollbars and such.
