What you can do is move the table.refresh(); code at the end of the child thread code and use SwingUtilities.InvokeLater to forward it to the GUI thread event queue:

 public void run() {
      //...
      SwingUtilities.InvokeLater(
            new Runnable() {
                 public void run() {
                     table.refresh();
                 }
            });         
 }

That way you are executing it on the GUI thread but only when the child thread finished its work.
