The UI locks up if the table has, let's say, 10,000,000 rows. I think in this case it should instead pick a reasonable limited range (maybe a max 1000 rows or so) of rows based on what's currently visible, so as not to lock up the UI. This might be a separate improvement.

Here is my jtable autofit column that uses sampling to avoid processing all rows:
