JTable how prepareEditor works

by

I think the prepareRenderer(...) code should be:

        public Component prepareRenderer(TableCellRenderer renderer, int row, int column) {
            Component c = super.prepareRenderer(renderer, row, column);

            if ((column == 2 || column == 3) && (Boolean)getValueAt(row, 0)) {
                return c;
            }

        //    if (column == 0 || column == 1 || (Boolean) getValueAt(row, 0)) {
            if (column == 0 || column == 1) {
                return c;
            }

            return Box.createRigidArea(c.getPreferredSize());
        }

Then you should get rid of the prepareEditor(...) code. Instead you should have more logic in the isCellEditable(...) method. Something like:

        public boolean isCellEditable(int row, int column) {

            if (column == 0) return true;

            if (column == 1 || column == 4 || column == 5) return false;

            return (Boolean)getValueAt(row, 0);
        }
