Java Checkers progress

I've continued working on my Java checkers program, and it has an interface similar to CheckerBoard now, and plays a decent game (albeit without opening or endgame databases). I also worked on a beginner level that will be less frustrating than CheckerBoard is now!
However, work on the interface is slow, as I feared. I want to add PDN support, and while writing a PDN parser was simple, I find it quite hard to use the Swing Table to display the games when loading them. Oh well, at some point I will either give up on the PDN feature and publish anyway or find out how to use it....
