如何通过单击按钮添加包含行和列的新JTable？

Question

我是Java的初学者，我需要帮助。

我想在点击按钮时在JFrame或JPanel中添加包含行和列的表格。如何通过单击按钮添加包含行和列的新表？

Answer 1

1. 首先，您必须将JButton添加到第
页
2. 在按钮
中添加ActionListener

3. 比按下按钮时列表

   JButton b = new JButton("Click Me");
   b.addActionListener(new ActionListener() {
   
   public void actionPerformed(ActionEvent e) {
   
   String[] columnNames = {"First Name",
               "Last Name",
               "Sport",
               "# of Years",
               "Vegetarian"};
   
   Object[][] data = {
               {"Kathy", "Smith",
                "Snowboarding", new Integer(5), new Boolean(false)},
               {"John", "Doe",
                "Rowing", new Integer(3), new Boolean(true)},
               {"Sue", "Black",
                "Knitting", new Integer(2), new Boolean(false)},
               {"Jane", "White",
                "Speed reading", new Integer(20), new Boolean(true)},
               {"Joe", "Brown",
                "Pool", new Integer(10), new Boolean(false)}
           };
   
       JTable table = new JTable(data, columnNames);
       add(table);
   
   }
   });
