下面的例子是我之前写过一次的表格模型。但是为了分类方便，我又重新弄了一次，将这段代码分为监听事件了。
import java.awt.*;
import java.awt.event.*;import javax.swing.*;
import javax.swing.event.*;
import javax.swing.event.TableModelListener;
import javax.swing.table.*;public class Main extends JFrame {private JTable table;// 声明一个表格对象private DefaultTableModel tableModel;// 声明一个表格模型对象private JTextField aTextField;private JTextField bTextField;public static void main(String args[]) {Main frame = new Main();frame.setVisible(true);}public Main() {super();setTitle("表格模型事件示例");setBounds(100, 100, 548, 213);setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);final JScrollPane scrollPane = new JScrollPane();getContentPane().add(scrollPane, BorderLayout.CENTER);String[] columnNames = { "A", "B" };String[][] rowValues = { { "A1", "B1" }, { "A2", "B2" },{ "A3", "B3" }, { "A4", "B4" } };// 创建表格模型对象tableModel = new DefaultTableModel(rowValues, columnNames);// 为表格模型添加事件监听器tableModel.addTableModelListener(new TableModelListener() {public void tableChanged(TableModelEvent e) {int type = e.getType();// 获得事件的类型int row = e.getFirstRow() + 1;// 获得触发此次事件的表格行索引int column = e.getColumn() + 1;// 获得触发此次事件的表格列索引if (type == TableModelEvent.INSERT) {// 判断是否有插入行触发System.out.print("此次事件由 插入 行触发，");System.out.println("此次插入的是第 " + row + " 行！");// 判断是否有修改行触发} else if (type == TableModelEvent.UPDATE) {System.out.print("此次事件由 修改 行触发，");System.out.println("此次修改的是第 " + row + " 行第 " + column+ " 列！");// 判断是否有删除行触发} else if (type == TableModelEvent.DELETE) {System.out.print("此次事件由 删除 行触发，");System.out.println("此次删除的是第 " + row + " 行！");} else {System.out.println("此次事件由 其他原因 触发！");}}});table = new JTable(tableModel);// 利用表格模型对象创建表格对象table.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);scrollPane.setViewportView(table);final JPanel panel = new JPanel();getContentPane().add(panel, BorderLayout.SOUTH);final JLabel aLabel = new JLabel("A：");panel.add(aLabel);aTextField = new JTextField(15);panel.add(aTextField);final JLabel bLabel = new JLabel("B：");panel.add(bLabel);bTextField = new JTextField(15);panel.add(bTextField);final JButton addButton = new JButton("添加");addButton.addActionListener(new ActionListener() {public void actionPerformed(ActionEvent e) {String[] rowValues = { aTextField.getText(),bTextField.getText() };tableModel.addRow(rowValues);// 向表格模型中添加一行aTextField.setText(null);bTextField.setText(null);}});panel.add(addButton);final JButton delButton = new JButton("删除");delButton.addActionListener(new ActionListener() {public void actionPerformed(ActionEvent e) {// 获得表格中的选中行int[] selectedRows = table.getSelectedRows();for (int row = 0; row < selectedRows.length; row++) {// 从表格模型中移除表格中的选中行tableModel.removeRow(selectedRows[row] - row);}}});panel.add(delButton);}
}运行结果：
