程序分三部分，主程序类SuperTable.java，框架类SuperTableFrame.java，数据模板类SuperTableModel.java。
   
     
      
       主程序类SuperTable.java，如下：
package supertable.swing;
import javax.swing.*;
      
public class SuperTable {
  public static void main(String[] args){
   JFrame frame = new SuperTableFrame();
   frame.show();
  }
}
      
      
     
   
  
   
  
框架类SuperTableFrame.java，如下： package supertable.swing; import java.awt.Container;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent; import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.TableModel; import javax.swing.Action;
import javax.swing.AbstractAction;
import javax.swing.Timer; /*

public class SuperTableFrame extends JFrame {
  private JTable table = null;
  private Timer timer = null;
  public SuperTableFrame(){
   timer = new Timer(300,updateTableAction);
   setTitle("SuperTable");
   setSize(300,200);
   addWindowListener(new WindowAdapter(){
    public void windowClosing(WindowEvent e){
     System.exit(0);
    }
   });
   TableModel model = new SuperTableModel(30,5,10);
   table = new JTable(model);
   
   JPanel p = new JPanel();
   addButton(p,"Update",new ActionListener(){
    public void actionPerformed(ActionEvent evt){
     table.validate();
     table.updateUI();
    }
   });
   addButton(p,"Start",new ActionListener(){
    public void actionPerformed(ActionEvent evt){
     timer.start();
    }
   });
   addButton(p,"Stop",new ActionListener(){
    public void actionPerformed(ActionEvent evt){
     timer.stop();
    }
   });
   Container contentPane = getContentPane();
   contentPane.add(new JScrollPane(table),"Center");
   contentPane.add(p,"South");
  }
  public void addButton(Container c,String title,ActionListener a){
   JButton b = new JButton(title);
   c.add(b);
   b.addActionListener(a);
  }
  private Action updateTableAction = new AbstractAction(){
   public void actionPerformed(ActionEvent e){
    table.validate();
    table.updateUI();
   }
  };
}
数据模板类SuperTableModel.java，如下： package supertable.swing; import java.text.NumberFormat; import javax.swing.table.AbstractTableModel;
public class SuperTableModel extends AbstractTableModel {
  private int years;
  private int minRate;
  private int maxRate;
  private static final double INITAL_BALANCE = 100000.0;
  public SuperTableModel(int y,int r1,int r2){
   years = y;
   minRate =r1;
   maxRate = r2;
  }
  public int getRowCount(){
   return years;
  }
  public int getColumnCount(){
   return maxRate -minRate +1;
  }
  public Object getValueAt(int r,int c){
   //double rate = (c + minRate)/100.0;
   //int nperiods = r;
   //double futureBalance = INITAL_BALANCE * Math.pow(1+rate,nperiods);
   
   double rate = Math.random();
   return NumberFormat.getCurrencyInstance().format(rate);
  }
  public String getColumnName(int c){
   double rate = (c+minRate)/100.0;
   return NumberFormat.getPercentInstance().format(rate);
  }
} 运行图：
