Hi all,
I have added a JTable inside a JScrollPane like this :

JTable table = new JTable();
JScrollpane scrollpane = new JScrollpane(table);

Now I want to remove the jtable and add a JPanel instead to the
scrollpane.
I tried this :

      JPanel panel = new JPanel();
      panel.add(new JLabel("hello"));
      scrollpane.getViewport().remove(table);
      scrollpane.getViewport().removeNotify();
      scrollpane.getViewport().repaint();
      scrollpane.getViewport().add(panel);

the table is removed but I can't see the added panel.
Am I doing something wrong ? Please some help would be very appreciated
!!
Thanks.

Nadia.
