Hi,everybody

as the title, I need the tableheader to be editable, and i rewrited the
CellEditor for the tableheader,
the code is as follows:

tableColumn.setCellEditor(new TableHeadEditor());

private class TableHeadEditor extends AbstractCellEditor implements
TableCellEditor{
    JTextField jTextField = new JTextField("????");
    public Component getTableCellEditorComponent(JTable table,
        Object value, boolean isSelected, int row, int column) {
            jTextField.setEditable(true);
            return jTextField;
        }
        public Object getCellEditorValue() {
            return null;
        }
    }
but it can't work at all,
is there somting wrong?

regards,
