Lon,
I think I misunderstood you first time.
You can create a class that extends from MouseAdapter and set it up so it would listen for a mouse click only. That way you can detect when user clicks on a checkbox. You need to pass the class to a table.addMouseListener(mouseAdapter) method.
I had an example of it somewhere, but I can't find it. Sorry
I hope it will help.
Lena.
