帮我解决jPopupMenu的问题

我在一张表上建了个JPopupMenu,怎么一让他出来后,表里面的内容都不见了,只有表的字段名.
下面是主要代码:

String[] name={"映像名称","用户名","CPU","内存使用","dfd"};

         String[][] data=new String[10][10];

         for(int i=0;i<data.length;i++)

             for(int j=0;j<data[i].length;j++)

                 data[i][j]=String.valueOf(1);

defaultModel=new DefaultTableModel(data,name);

        jTable1=new JTable(defaultModel);

        jTable1.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);

PopupPanel pp=new PopupPanel(); 

jTable1.add(pp);

public class PopupPanel extends JPanel implements MouseListener,PopupMenuListener,

                                 ActionListener{

    public JPopupMenu Popup=null;

    public PopupPanel(){

        Popup = new JPopupMenu();

        JMenuItem theItem;

        JMenuItem killProsess = new JMenuItem("结束进程(E)");

        JMenuItem setFirst = new JMenuItem("设置优先级(p)");

        killProsess.setMnemonic('E');

        setFirst.setMnemonic('P');

        Popup.add(theItem=killProsess);

        Popup.add(theItem=setFirst);

        theItem.addActionListener(this);

        Popup.setBorder(new BevelBorder(BevelBorder.RAISED));

        Popup.addPopupMenuListener(this);

        addMouseListener(this);

    }

    public void mouseClicked(MouseEvent me){checkPopup(me);}

    public void mousePressed(MouseEvent me){checkPopup(me);}

    public void mouseReleased(MouseEvent me){checkPopup(me);}

    public void mouseExited(MouseEvent me){}

    public void mouseEntered(MouseEvent me){}

    

    private void checkPopup(MouseEvent me){

        if(me.isPopupTrigger()){

            Popup.show(me.getComponent(),me.getX(),me.getY());

        }

    }

    public void popupMenuWillBecomeVisible(PopupMenuEvent pme){}

    

    public void popupMenuWillBecomeInvisible(PopupMenuEvent pme){}

    

    public void popupMenuCanceled(PopupMenuEvent pme){}

    

    public void actionPerformed(ActionEvent ae){}

}
