javax.swing.event.TableModelEvent
TableModelEvent is used to notify listeners that a table model has changed. The model event describes changes to a TableModel and all references to rows and columns are in the co-ordinate system of the model. Depending on the parameters used in the constructors, the TableModelevent can be used to specify the following types of changes:
TableModelEvent(source); // The data, ie. all rows changed TableModelEvent(source, HEADER_ROW); // Structure change, reallocate TableColumns TableModelEvent(source, 1); // Row 1 changed TableModelEvent(source, 3, 6); // Rows 3 to 6 inclusive changed TableModelEvent(source, 2, 2, 6); // Cell at (2, 6) changed TableModelEvent(source, 3, 6, ALL_COLUMNS, INSERT); // Rows (3, 6) were inserted TableModelEvent(source, 3, 6, ALL_COLUMNS, DELETE); // Rows (3, 6) were deleted
It is possible to use other combinations of the parameters, not all of them are meaningful. By subclassing, you can add other information, for example: whether the event WILL happen or DID happen. This makes the specification of rows in DELETE events more useful but has not been included in the swing package as the JTable only needs post-event notification.
Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see XMLEncoder.

The cells from (firstRow, column) to (lastRow, column) have been changed. The column refers to the column index of the cell in the model's co-ordinate system. When column is ALL_COLUMNS, all cells in the specified range of rows are considered changed.
The type should be one of: INSERT, UPDATE and DELETE.
