The AbstractTableMoeel doesn't support this. If you extend the AbstractTableModel to create a custom model then you need to implement this method yourself.

Or you can use the DefaultTableModel which implements a setRowCount() method. So you can reset the rows to 0. You can then use the insertRow(...) method to add new rows.

However the easier way is to probably just create a new TableModel. Then you can refresh the table by using:

table.setModel( newlyCreatedModel );
