1 /**
2  * In a chain of data manipulators some behaviour is common. TableM1
3  * provides most o1 this behavour and can be subclassed by filters
4  * that only need to override a handful of specific methods. TableMap
5  * implements TableModel by routing all requests to its model, and
6  * TableModelListener by routing all events to its listeners. Inserting
7  * a TableMap which has not been subclassed into a chain of table filters
8  * should have no effect.
