Answer 4

you should only add a new column with setting its picklist property

Answer 5

首先告诉你,在column里可以加button,但是我看你的目的是弹出一个popup画面.
所以根本用不着那么麻烦.这样就可以了.
public class t extends JTable{
  public t(){
    addMouseListener(new MouseListener(){
    public void  mouseClicked(MouseEvent e)
    {
     if(!(e.getModifiers()==e.META_MASK)){//clicked mouse left
       JPopupMenu l= new JPopupMenu();                   
       l.show(参数);
     }
     if (e.getModifiers()==e.META_MASK){//clicked mouse right
       JPopupMenu r= new JPopupMenu();    
       r.show(参数);               
     }
     }
            public void  mouseEntered(MouseEvent e){}
            public void  mouseExited(MouseEvent e){}
            public void  mousePressed(MouseEvent e){}
            public void  mouseReleased(MouseEvent e){}
        });
    }
  }
}
