The JTreeTable class is new Swing component that merges a JTree with a JTable. Considering that you
don't have to write either the tree or the table yourself, it might be surprising how tricky it can be to
synchronize the two components.No more wasting your time on this, just plug in a
JTreeTable instead. The JTreeTable acts as a normal Swing component and also as a visual
shell around your code ensuring that the tree and the table handles events, colors and selections
in a conforming way.
