26  * In a chain of data manipulators some behaviour is common. TableMap
27  * provides most of this behaviour and can be subclassed by filters
28  * that only need to override a handful of specific methods. TableMap
29  * implements TableModel by routing all requests to its model, and
30  * TableModelListener by routing all events to its listeners. Inserting
31  * a TableMap which has not been subclassed into a chain of table filters
32  * should have no effect.
