You need to add following chunk of code, 

    table.addMouseListener(new MouseAdapter() {
        public void mouseClicked(MouseEvent e) {
            // This is for double click event on anywhere on JTable
            if (e.getClickCount() == 2) {
                JTable target = (JTable) e.getSource();
                int row = target.getSelectedRow();
                int column = target.getSelectedColumn();
               // you can play more here to get that cell value and all
                new DialogYouWantToOpen(row, Column);
            }
        }

    });

A Dialog which will be opened on double click.

class DialogYouWantToOpen extends JDialog{
       JLabel testLabel = new JLable();
       public DialogYouWantToOpen(int row, int column){
         setSize(200,200)
         setLayout(new FlowLayout());
         testLabel.setText("User double clicked at row "+row+" and column "+ column);
         add(testLabel);
       }

}

Generaly it should go something like this

Listener listener = new Listener() {
  public void handleEvent(Event e) {
    TableColumn column = (TableColumn) e.widget;
    System.out.println(column);
  }
};

you get the column out of event and then do what you want with it.
