Swing建立表格範例

下面的範例展示了如何在Java Swing應用程式中建立表格。

使用以下API -

• JTable(Object[][] data, String[] columnNames) - 建立表格。

範例

package com.yiibai.swingdemo;

import java.awt.FlowLayout;
import java.awt.GridLayout;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;

public class SwingTester {
   private JFrame mainFrame;
   private JLabel headerLabel;
   private JLabel statusLabel;
   private JPanel controlPanel;

   public SwingTester(){
      prepareGUI();
   }
   public static void main(String[] args){
      SwingTester swingControlDemo = new SwingTester();      
      swingControlDemo.showTableDemo();
   }
   private void prepareGUI(){
      mainFrame = new JFrame("Swing建立表格範例(tw511.com)");
      mainFrame.setSize(500,400);
      mainFrame.setLayout(new GridLayout(3, 1));

      mainFrame.addWindowListener(new WindowAdapter() {
         public void windowClosing(WindowEvent windowEvent){
            System.exit(0);
         }        
      });    
      headerLabel = new JLabel("", JLabel.CENTER);        
      statusLabel = new JLabel("",JLabel.CENTER);    
      statusLabel.setSize(350,100);

      controlPanel = new JPanel();
      controlPanel.setLayout(new FlowLayout());

      mainFrame.add(headerLabel);
      mainFrame.add(controlPanel);
      mainFrame.add(statusLabel);
      mainFrame.setVisible(true);  
   }
   private void showTableDemo(){
      headerLabel.setText("Control in action: JTable"); 

      String[] columnNames = {"姓名", "性別", "年齡", "薪水"};
      Object[][] data = {
         {"張三", "男", 27, 15000},
         {"李四",  "女", 24, 9500},
         {"王五",  "F", 34, 18000},
      };
      JTable table = new JTable(data, columnNames);
      JScrollPane scrollPane = new JScrollPane(table);
      scrollPane.setSize(300, 300);
      table.setFillsViewportHeight(true);
      controlPanel.add(scrollPane);      
      mainFrame.setVisible(true);     
   } 
}

執行上面範例程式碼，得到以下結果：
