JTable数据的动态更新

最近要用到这个东西，网上的资料挺多可是没有一个完整的例子，这问题看好一会才弄出来了啊。现在贴出来也许对别人还有借鉴的用处。

package Gsgl;
import java.awt.Dimension;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.Vector;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;

public class test extends JFrame implements ActionListener{
static int i=0;
JTable table=new JTable();
JScrollPane src;
//DefaultTableModel model;
public test(){
//JTable table=new JTable();
this.setLayout(null);
this.gettable();
src=new JScrollPane(table);
src.setBounds(0, 0, 500, 200);
JButton b1=new JButton("变化");
b1.addActionListener(this);
b1.setBounds(0, 220, 60, 25);
this.add(src);
this.add(b1);
this.setSize(new Dimension(500,300));
this.setVisible(true);
}
public static void main(String args[]){
new test();
}
public void gettable(){
//System.out.println("@@@@@@@@@@@@@@"+i);
Vector v2=new Vector();
Vector v3=new Vector();

Vector v5=new Vector();
Vector v6=new Vector();
//String ss[]={"100","200","300","400"};
if(i==0){
for(int j=0;j<3;j++){
Vector v1=new Vector();
v1.addElement((j+1)*10);
v1.addElement((j+2)*100);
v2.addElement(v1);
}
v3.addElement("A");
v3.addElement("B");
DefaultTableModel model=new DefaultTableModel(v2,v3);
//System.out.println("###############"+model.toString());
table.setModel(model);
table.repaint();
table.updateUI();
//table=new JTable(v2,v3);
}
if(i==1){
for(int k=2;k<4;k++){
Vector v4=new Vector();
v4.addElement((k+5)*10);
v4.addElement((k+6)*100);
v5.addElement(v4);
}
v6.addElement("C");
v6.addElement("D");
DefaultTableModel model=new DefaultTableModel(v5,v6);
table.setModel(model);
table.repaint();
table.updateUI();
}
}
public void actionPerformed(ActionEvent e) {
// TODO Auto-generated method stub
if(e.getActionCommand().equals("变化")){
i=1;
this.gettable();
}
}
}
如果有啥问题可以交流.(scdn上我几乎天天在).
