How to create expanding Tables (Web 2.0 Style) with Swing ?

Hi There,

As I am working on a GUI for a little Aplication of mine, I am
wondering how to create expanding Table Rows with Swing. I whish to
have Table Rows that can, for Example by clicking or hovering the
Mousecursor over them, expand and show additional Info to the
coresponding Row.
I could do this with Tolltips, but I would prefere to have the Row
expand and stay that way until some other action occurs. The Pictur i
have in Mind about it is simmilar to the Tables that work with hidden
layers senn on so many Websites on the Internet.

Any Suggestions and IDeas are welcome,

thanks for your efforts,

Sungu
