JTable is not allowing editing cells in MySaifu, I am making the cells editable overriding the method of the class javax.swing.table.DefaultTableModel.

The following code reproduce the bug.

public class TableTest extends JFrame {

	public TableTest(String title) {
		super(title);
		setSize(150, 150);
		addWindowListener(new WindowAdapter() {
			public void windowClosing(WindowEvent we) {
				dispose();
				System.exit(0);
			}
		});
		init();
		pack();
		setVisible(true);
	}

	private void init() {
		JTable jt = new JTable(new TestTableModel());
		JScrollPane pane = new JScrollPane(jt);
		getContentPane().add(pane);
	}
	
	public static void main(String[] argv) {
		new TableTest("JTable Example");
	}
}

public class TestTableModel extends DefaultTableModel {

	private static Object data[][] = { { "John", "Sutherland", "Student" },
			{ "George", "Davies", "Student" },
			{ "Melissa", "Anderson", "Associate" },
			{ "Stergios", "Maglaras", "Developer" }, };

	private static Object fields[] = { "Name", "Surname", "Status" };
	
	public TestTableModel() {
		super(data, fields);
	}
	
	public boolean isCellEditable(int row, int column) {
		return true;
	}
}

Be able of edit JTable cells is very important to improve usability of the user inteface in my system.
