java.swing 图形用户界面 怎样添加表格

public class Stmessege1 extends JFrame {

private static final long serialVersionUID = 1L

private JTable table// 声明表格

void Stmessege11() {

setSize(460, 320)

setVisible(true)

}

public Vector getDataVector() throws SQLException, ClassNotFoundException {

Connection conn = null

java.sql.Statement stmt = null

Class.forName("com.mysql.jdbc.Driver")

String dburl = "jdbc:mysql://localhost:3306/hp"

String dbuser = "root"

String dbpassword = "19920102"

conn = DriverManager.getConnection(dburl, dbuser, dbpassword)

stmt = conn.createStatement()

String sql = "select* from xsgli"

ResultSet rs = stmt.executeQuery(sql)

Vector dataVector = new Vector()

while (rs.next()) {

Vector rowVector = new Vector()

for (int i = 1i <= 7i++) {

if (i == 2 || i == 4) {

rowVector.add(String.valueOf(rs.getInt(i)))

} else {

rowVector.add(rs.getString(i))

}

}

dataVector.add(rowVector)

}

return dataVector

}

public Vector getColumnVector() {

Vector columnVector = new Vector()

columnVector.add("姓名")

columnVector.add("学号")

columnVector.add("性别")

columnVector.add("班级")

columnVector.add("系别")

columnVector.add("成绩")

columnVector.add("专业")

return columnVector

}

public Stmessege1() throws SQLException, ClassNotFoundException {

super()

setTitle("学生学籍数据显示")

setBounds(100, 100, 382, 223)

// setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE)

Connection conn = null

Statement stmt = null

Class.forName("com.mysql.jdbc.Driver")

String dburl = "jdbc:mysql://localhost:3306/hp"

String dbuser = "root"

String dbpassword = "19920102"

conn = DriverManager.getConnection(dburl, dbuser, dbpassword)

java.sql.Statement st = conn.createStatement()

String sql = "select* from xsgli"

ResultSet rs = st.executeQuery(sql)

Vector columnVector = getColumnVector()

Vector dataVector = getDataVector()

final JScrollPane scrollPane = new JScrollPane()

getContentPane().add(scrollPane, BorderLayout.CENTER)

table = new JTable(dataVector, columnVector)

table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF)

scrollPane.setViewportView(table)

}

}

希望能帮到你，谢谢采纳

你指的文本区域是jtextarea这个吗?你要在那里在加入一个jtable??好像不好实现啊..不过还是有办法..自己封装一个组件..实现jtextarea和jtable的功能.因为你不用扩展新的功能.只用原有的功能就够了.主要就是样子搞的好看点就行了.打印的时候把数据全都打印出来就好了...

String[] tableName = {"IP","主机名"}

Object [][] lanwa={}

Class []datatype={ String.class, String.class }

DefaultTableModel tableModel = new DefaultTableModel(lanwa,tableName)

JTable table = new JTable(tableModel)

JPanel jPanel1 = new JPanel()

JScrollPane jScrollPane1 = new JScrollPane(table)

将jpanel加在frame中就行了

显示多个空行将

String [] lineForAdd = {"",""}

tableModel.addRow(lineForAdd)

多执行几次就行了
