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