12  * In a chain of data manipulators some behaviour is common. TableMap
13  * provides most of this behavour and can be subclassed by filters
14  * that only need to override a handful of specific methods. TableMap
15  * implements TableModel by routing all requests to its model, and
16  * TableModelListener by routing all events to its listeners. Inserting
17  * a TableMap which has not been subclassed into a chain of table filters
18  * should have no effect.
