Thanks for your reply!
Finally I have decided to extend the DefaultTableModel because I have not found how to do! lol
When I created an "addRow" methode in my model (extending the AbstractTableModel), I had a probleme with the data array : when I tried to extend it by adding a row, I get an error.
My data array was defined with x row, and here, there was now y row, with y>x, so it was out of bounds.
But I am not graduate from any
Java High school (lol) so... I learn every hour and this is really interesting!
Thanks again, take care
