A UI element as you describe might be more elegant but the code 
implementing it on top of a JTable would likely be very inelegant.
It seems that quite a few have attempted it with varying degrees of success.
The main stumbling block is that the JTable grid that you see onscreen 
is not a grid of Components, rather an image put together by the JTable 
using it's TableCellRender(s).
