Thanks for the clarification. We were talking about completely different screens - originally you had said “the matching window” which in my head is the Step 2 page with the Matches in library/possible matches for selected book grids. Whereas you are talking about the CSV preview on step 1 and books in list on step 2. Picture worth a thousand words and all that!

I now understand what you mean and can look to make a few tweaks. But I think the easiest solution for now is to either just not use resizeColumnsToContents() on those grids in case of outliers, or use it but then go through and check if any sizes are wider than the current grid width and shrink them down. Also I believe there is a HorizontalScrollMode which can be changed on the grid to Pixel, so it would allow the manual resizing even if your column goes super large by manually double clicking the column header.
