  43  * In a chain of data manipulators some behaviour is common. TableMap
  44  * provides most of this behavour and can be subclassed by filters
  45  * that only need to override a handful of specific methods. TableMap
  46  * implements TableModel by routing all requests to its model, and
  47  * TableModelListener by routing all events to its listeners. Inserting
  48  * a TableMap which has not been subclassed into a chain of table filters
  49  * should have no effect.
