如何在JPanel内加入JTable呢？

package com.bonc.mp.excplme

import javax.swing.JPanel

import javax.swing.JFrame

import javax.swing.JTable

import java.awt.Rectangle

public class Rusult extends JFrame {

private static final long serialVersionUID = 1L

private JPanel jContentPane = null

private JTable jTable = null

public Rusult() {

super()

initialize()

}

private void initialize() {

this.setSize(300, 200)

this.setContentPane(getJContentPane())

this.setTitle("JFrame")

}

private JPanel getJContentPane() {

if (jContentPane == null) {

jContentPane = new JPanel()

jContentPane.setLayout(null)

jContentPane.add(getJTable(), null)

}

return jContentPane

}

private JTable getJTable() {

if (jTable == null) {

jTable = new JTable()

jTable.setBounds(new Rectangle(3, 18, 172, 91))

}

return jTable

}

}

给分吧！！ 呵呵 ~~

因为BorderLayout的布局原理导致这样的，四个角的组件的展示大小是它的preferSize，很不幸Table默认的preferSize是0，所以你放上去是看不到的。你可以设置下Table的PreferSize你就可以看见，不过建议你还是把Table放在Center这个位置。

还有添加JTable的时候别忘了把JTable放在JScrollPane中。

//给你写了个完整的小例子~~ 你看看吧

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()

dtm.insertRow(dtm.getRowCount(), temp)

}

}
