Sort JTable Data on Column Header Click

[Hewa Naimanage Sumedha Amalka]

Hi all,
Im trying to sort a jTable on column click, but when I insert the mouse click event; my panel is not updating with sorted table.

I used sorting algo in a separated class and code is working properly if I remove the header click event and uncomment other stuffs in bottom

class SortableTable extends JFrame {

    DefaultTableModel model = new DefaultTableModel(new Object[][]{{"A", "1"},
                {"M", "2"}, {"A", "3"}, {"L", "4"}, {"K", "5"}, {"A", "6"}}, new Object[]{
                "Column No1", "Column No2"});
    JTable tableOrig = new JTable(model);
    JTable tableSorted;
    JTableHeader tableHeader = tableOrig.getTableHeader();
    JPanel panel = new JPanel();

    public SortableTable() {

        tableHeader.addMouseListener(new MouseAdapter() {

            @Override
            public void mouseClicked(MouseEvent e) {
                JTableHeader tableHeader = (JTableHeader) e.getSource();
                int selectedColumn = 0;
                selectedColumn = tableHeader.columnAtPoint(e.getPoint());
                if (selectedColumn != -1) {
                    tableSorted = new JTable(new SampleSortingTableModel(model, selectedColumn));
                    tableSorted.setAutoResizeMode(JTable.AUTO_RESIZE_ALL_COLUMNS);
                    panel.add(new JScrollPane(tableSorted));
                    panel.validate();
                    tableSorted.revalidate();
                    panel.repaint();
                    getContentPane().add(panel, BorderLayout.CENTER);
                    getContentPane().repaint();
                    System.out.println("SORTING COLUMN " + selectedColumn);
                }
            }
        });

      //  tableSorted = new JTable(new SampleSortingTableModel(model, 0));
     //   tableSorted.setAutoResizeMode(JTable.AUTO_RESIZE_ALL_COLUMNS);
     //  JPanel panel = new JPanel(new GridLayout(1, 2));

        panel.add(new JScrollPane(tableOrig));
     //   panel.add(new JScrollPane(tableSorted));
        getContentPane().add(panel, BorderLayout.CENTER);
        this.setDefaultCloseOperation(DISPOSE_ON_CLOSE);
        pack();


    }

    public static void main(String arg[]) {
        new SortableTable().setVisible(true);
    }
}

thanks in advance !

> my panel is not updating with sorted table.

actually, it is - you can't see it because 'panel' is a FlowLayout.
run the program, click a header, now drag the frame real wide (so there's enough space to show the 2 tables)

you can either
change 'panel' to a more suitable LayoutManager, or better
change the model of the visible table (instead of creating another table)

It worked... thanks Michael...
