How to fire event when JTable is resized?

After fooling around with custom table models for a while, I decided life would be made simpler by implementing the JTable using HTML tables for the cells- columns essentially are either left-justified or right-justified, with the widest entry centered within the column (just for fun, I also highlight the bad-duration-formats in pink).
However, this means that the html table cells should be rewritten if the app is resized horizontally. How do you hook into a resizing event?

Hi Thomas,
Man, you're really into pushing the edge of the envelope aren't you? Look at JViewport and JViewport.ViewListener which has a method: void componentResized(ComponentEvent e). That should give you a starting point.
Hope this helps,

You're not the first person to make such an observation- it's amazing that I'm still living.
Table cells a.y.k. are just JLabels, which have no margin property. However I realized I could achieve a margin by using a 1pixel.gif icon and setting iconTextGap.
But then- since you need different margins for each column- it appeared I'd need a different custom class for each column...
