        {
            table.setDefaultRenderer( Class.forName
               ( "java.lang.Integer" ), renderer );
        }
        catch( ClassNotFoundException ex )
        {
            System.exit( 0 );
        }
        JFrame frame = new JFrame();
        frame.addWindowListener( 
            new WindowAdapter() 
            {
                public void windowClosing(WindowEvent e) 
                {
                    System.exit(0);
                }
            }
        );
        frame.getContentPane().add( table );
        frame.pack();
        frame.setVisible( true );
    }
}


The code snippet table.setDefaultRenderer( Class.forName( "java.lang.Integer" ), renderer ); tells the table to use the custom cell renderer for any cell that contains an integer. You can also set a table's renderer by setting the proper TableColumn object directly.
