NSCell objects in tables can also be a pain. We wanted to have a 
small table that had cells with tracking rects so that we could have 
rollover buttons that worked. We've managed to hack it to work 
(without subclassing NSTableView) but it wasn't easy. It would be 
nice if NSCell objects had this support. It would also be useful if 
NSTableView objects could support NSView objects (which would suit 
when you only had a small table).
