Now I can be more specific:
The correct TableCellEditor is used
and the correct TableCellEditor's
Component is used, the only thing what is wrong:

I do not get any key-event until I click into the tablecell!!!

I added a DocumentListener to my TableCellEditor's
Component: this works fine!!

If you know a way to make the TableCellEditor's
Component's KeyListener to receive the keyevents without
using the mouse before, I will be happy to get
your answer!

Thanx, Martin
