3. JTable Model

The listener will be notified of any addition, removal, movement, or selection of columns, or changing of column margins.

public interface TableColumnModelListener extends EventListener {
  public void columnAdded(TableColumnModelEvent e);
  public void columnMarginChanged(ChangeEvent e);
  public void columnMoved(TableColumnModelEvent e);
  public void columnRemoved(TableColumnModelEvent e);
  public void columnSelectionChanged(ListSelectionEvent e);
}





TableColumnModelListener tableColumnModelListener =
    new TableColumnModelListener() {
  public void columnAdded(TableColumnModelEvent e) {
    System.out.println("Added");
  }
  public void columnMarginChanged(ChangeEvent e) {
    System.out.println("Margin");
  }
  public void columnMoved(TableColumnModelEvent e) {
    System.out.println("Moved");
  }
  public void columnRemoved(TableColumnModelEvent e) {
    System.out.println("Removed");
  }
  public void columnSelectionChanged(ListSelectionEvent e) {
    System.out.println("Selected");
  }
};
