Need help with JTable in Applet

[Scott Parmley]

Hello everyone!
I'm having trouble with JTable in an applet. I'm trying to make a dynamic table useable in an applet. My problem may be less about the applet it self and more about JTable. Currently, I am using DefaultTableModel and DefaultTableColumnModel in my implementation. I setup the DefaultTableColumnModel first, and later use the DefaultTableModel to add/delete rows dynamically. The problem arises with the TableModel. When editing is finished in a cell, all the cells of that row replicate the value of the edited cell.
I'm really not sure what I'm missing here, so any help here would be MUCH appreciated.
Thanks very much,
-Scott
