代码如下:
package com.webmonitor;
import java.awt.BorderLayout;
import java.awt.Dimension;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTable;
public class WebMonitor extends JFrame {
JPanel contentPane;
BorderLayout borderLayout1 = new BorderLayout();
String[] columnNames = {"URL","网站名称","Price"};
Object[][] data =
{
{"http://www.google.com", new Integer(5),"5.00"},
{"http://www.chinaip.net", new Integer(3),"6.00"},
{"http://www.officebill.net", new Integer(2),"4.00"},
{"Grapes", new Integer(3),"2.00"},
};
JTable jTable1 = new JTable(data,columnNames);
public WebMonitor() {
try {
setDefaultCloseOperation(EXIT_ON_CLOSE);
jbInit();
} catch (Exception exception) {
exception.printStackTrace();
}
}
private void jbInit() throws Exception {
contentPane = (JPanel) getContentPane();
contentPane.setLayout(borderLayout1);
setTitle("网站监控(WebMonitor) v1.0");
jTable1.setSize(new Dimension(300, 80));
// jTable1.setPreferredScrollableViewportSize(new Dimension(300, 80));
setSize(new Dimension(400, 300));
this.show();
contentPane.add(jTable1, java.awt.BorderLayout.CENTER);
}
public static void main(String args[])
{
new WebMonitor();
}
}
为什么没有表头?
先把jtable放到JScrollPane就有表头了。
