按照你的要求添加两个按钮的Java程序如下:
package com.sunshine.customer;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.table.DefaultTableModel;
public class JTableDemo extends JFrame implements ActionListener{
private JPanel topPanel;
private JTable table;
private JButton addRoom=new JButton("添加房间");
private JButton removeRoom=new JButton("删除房间");
private DefaultTableModel dtm;
public JTableDemo(){
  setTitle( "Simple JTable Application" );
  setSize(560, 400 );
  setBackground( Color.gray );
  topPanel = new JPanel();
  topPanel.setLayout( new BorderLayout() );
  getContentPane().add( topPanel );
  String cols[] = {"房间号","是否预定","房间价格","房间类型","房间状态","卫生情况","剩余时间"};
  String rowData[][] = {{ "", "", "","","","",""},
    { "", "", "","","","",""},{ "", "", "","","","",""},{ "", "", "","","","",""},
    { "", "", "","","","",""},{ "", "", "","","","",""},{ "", "", "","","","",""},
    { "", "", "","","","",""},{ "", "", "","","","",""},{ "", "", "","","","",""},
    { "", "", "","","","",""},{ "", "", "","","","",""},{ "", "", "","","","",""},};
  dtm=new DefaultTableModel();
  dtm.setDataVector(rowData, cols);
  table = new JTable(dtm);
  JScrollPane scrollPane = new JScrollPane(table);
  topPanel.add( scrollPane, BorderLayout.CENTER );
  addRoom.addActionListener(this);
  removeRoom.addActionListener(this);
  JPanel p=new JPanel();
  p.add(addRoom);
  p.add(removeRoom);
  topPanel.add( p,BorderLayout.SOUTH );
}
public static void main( String args[] ) {
  JTableDemo mainFrame = new JTableDemo();
  mainFrame.setVisible( true );
}
@Override
public void actionPerformed(ActionEvent ae) {
  if(ae.getSource()==addRoom){
   String row[]={ "", "", "","","","",""};
   dtm.addRow(row);
  }
  if(ae.getSource()==removeRoom){
   dtm.removeRow(table.getSelectedRow());
  }
}
}
