import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;

public class testjtable extends JFrame {
private String[] columnNames = ;

private Object[][] rowData = new Object[][] {};

private DefaultTableModel tableModel = new DefaultTableModel(rowData,
columnNames);
public static void main(String args[]) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
testjtable frame = new testjtable();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}

/**
* Create the frame
*/
public testjtable() {
super();
setBounds(100, 100, 500, 375);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

final JPanel panel = new JPanel();
panel.setLayout(null);
getContentPane().add(panel, BorderLayout.CENTER);

final JScrollPane scrollPane = new JScrollPane();
scrollPane.setBounds(0, 0, 492, 342);
panel.add(scrollPane);

final JTable table = new JTable(tableModel);
scrollPane.setViewportView(table);

//添加实例
Vector memory = new Vector();
memory.add(1);
memory.add(2);
memory.add(3);
memory.add(4);
memory.add(5);
memory.add(6);
memory.add(7);
memory.add(8);
tableModel.addRow(memory); // 增加行
