How to JTable - Editors and Renderers[^]

you might want to read that.

You can deal with the TableCellRenderer. But that's fancy.

Much simpler, faster, easier and therefor recommended: This approach[^]

They simply overwrote the function

 public boolean isCellEditable(int rowIndex, int colIndex) {
      return false; //Disallow the editing of any cell
}

in JTable to give the specified allowance.

I thought that, but I want to find another way that don't need to override function. If there is not really anyway that better than this way. I must use it

That is the best way to do it. this is the principle of OO, take what's there and extend, i.e. override, methods that you want to act differently.

I normally don't use native Components - I always extend them. You can pass additional arguments if you want, in this case e.g. the enabled or disabled columns.

But you can use another approach: when your listener object reacts on the action, you can check whether it's an allowed column or not. But I think that gives a wrong feeling of an editable cell to the user when it is not.
