Answer 1

//给你个小例子看看

import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.*;
import javax.swing.table.DefaultTableModel;

public class TableTest implements ActionListener{

JFrame frame = new JFrame("JTable Test");
JButton button = new JButton("增加");
JTextField fname = new JTextField(20);
JTextField lname = new JTextField(20);
JPanel north = new JPanel();
JLabel l1 = new JLabel("姓名");
JLabel l2 = new JLabel("联系方式");
DefaultTableModel dtm = new DefaultTableModel(0, 2);
JTable table = new JTable(dtm);
JScrollPane jsp = new JScrollPane(table);
String [] temp = new String[2];

public void init() {
frame.setBounds(200, 200, 640, 480);
frame.setLayout(new BorderLayout());
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setResizable(false);
north.add(l1);
north.add(fname);
north.add(l2);
north.add(lname);
button.addActionListener(this);
north.add(button);
dtm.setColumnIdentifiers(new String[] {"姓名", "联系方式"});
frame.add(north, BorderLayout.NORTH);
frame.add(jsp, BorderLayout.CENTER);
frame.setVisible(true);
}

public static void main(String[] args) {
TableTest tt = new TableTest();
tt.init();
}

public void actionPerformed(ActionEvent e) {
temp[0] = fname.getText();
temp[1] = lname.getText();
System.out.print(dtm.getRowCount());
dtm.insertRow(dtm.getRowCount(), temp);
}

}
