利用AbstractTableModel创建自己的table

包括2个java文件:  TableTEST.java 和 MyTableModel.java.

//  1. TableTEST.java ///

import java.awt.*;

import java.awt.event.*;

import javax.swing.*;

import javax.swing.table.*;

import java.util.*;

public class TableTEST extends JFrame {

 // 数据源 String tableHeads[] = { “A”, “B”, “C”, “D”, “E” };

 String tableContent[][] = { { “abc”, “def”, “ghi”, “jkl” },
   { “pqr”, “stu”, “vwx”, “yza” },
   { “efg”, “hij”, “klm”, “nop” },

 JTextField txtboxContent = new JTextField(10);

 JPanel pnlSouth = new JPanel(new GridLayout(1, 6));

 MyTableModel tbModel = new MyTableModel();

 // 生成模型类对象

 public TableTEST() { // 初始化窗体 super(“DO A Test!”);

  this.setBounds(50, 50, 500, 400);

  // 获取contentPane

  Container contentPane = getContentPane();

  contentPane.setLayout(new BorderLayout());

  // 初始化表格数据及表头

  tbModel.data = new Vector(1, 1);

  for (int i = 0; i < 5; i++)

   for (int j = 0; j < 4; j++)

    // 实现双击
    {

     int row = ((JTable) e.getSource()).rowAtPoint(e.getPoint()); // 获得行位置

     int col = ((JTable) e.getSource()).columnAtPoint(e
       .getPoint()); // 获得列位置
     String cellVal = (String) (tbModel.getValueAt(row, col)); // 获得点击单元格数据
     txtboxRow.setText((row + 1) + “”);
     txtboxCol.setText((col + 1) + “”);

     txtboxContent.setText(cellVal);

    } else
     return;

  });

  this.addWindowListener(new WindowAdapter() {

   public void windowClosing(WindowEvent me) {

//  2. MyTableModel.java ///

public Vector titles;
