swing中JTable的使用方法

 public static void main(String[] args) {

         Student s1 = new Student("张三", "001", 0);
         Student s2 = new Student("李四", "002", 1);
         Student s3 = new Student("王五", "003", 0);

         Vector<Object> row1 = new Vector<Object>();
         row1.add(s1.getName());
         row1.add(s1.getNumber());
         row1.add(s1.getAbsentTimes());

         Vector<Object> row2 = new Vector<Object>();
         row2.add(s2.getName());
         row2.add(s2.getNumber());
         row2.add(s2.getAbsentTimes());

         Vector<Vector<Object>> studentData = new Vector<Vector<Object>>();
         Vector<String> columnNames = new Vector<String>();

         studentData.add(row1);
         studentData.add(row2);

         columnNames.add("姓名");
         columnNames.add("编号");
         columnNames.add("缺考次数");

         JTable table = new JTable(studentData, columnNames);

         JFrame f = new JFrame();

         JScrollPane scrollPane = new JScrollPane(table);
         f.getContentPane().add(scrollPane, BorderLayout.CENTER);
         f.setVisible(true);
         f.setSize(500, 500);
         f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

     }
