Change value in column on select JComboBox?

In your Table Model's setValue method, when you have a change in column 0 call setValue again for column 1 with the value you want in column 1.

A TableModelListener will let you be notified of changes in a cell's value. Once notified you use that information to change the value in your other cells via setValue as jzd mentions.

Please read this tutoriar download.oracle.com/javase/tutorial/uisw... example shows basic workaround for TableCellEditor, tons of examples for that java2s.com/Code/Java/Swing-JFC/CatalogSw... subfolder java2s.com/Code/Java/Swing-JFC/Table-Ren....

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
