在核心java中创建GUI时的swing问题

Question

我必须使用swing在核心java中创建这种GUI：

在此GUI中：

1, 2, 3, 4... numbers are labels. These values are fixed.

A, B, C, D... are editable textfield. User can enter any value here.

我的方法是：使用表格并在其中放入两个文本字段。但我不知道怎么做

有没有其他简单的方法可以在核心java中实现这一部分

考虑到所示的要求，nested网格可能是一个有用的起点

import java.awt.Color;
import java.awt.EventQueue;
import java.awt.GridLayout;
import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTextField;

/**

 */
public class GridTest {

    private static final int N = 12;

    private void display() {
        JFrame f = new JFrame("GridTest");
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JPanel panel = new JPanel(new GridLayout(3, 4));
        for (int i = 0; i < N; i++) {
            panel.add(createPanel(i));
        }
        f.add(new JScrollPane(panel));
        f.pack();
        f.setLocationRelativeTo(null);
        f.setVisible(true);
    }

    private static JPanel createPanel(int i) {
        JPanel panel = new JPanel(new GridLayout(2, 2, 8, 8));
        panel.setBorder(BorderFactory.createLineBorder(Color.black));
        panel.add(new JLabel(String.valueOf(i)));
        panel.add(new JLabel());
        panel.add(new JLabel());
        panel.add(new JTextField(String.valueOf(Character.valueOf((char) ('A' + i)))));
        return panel;
    }

    public static void main(String[] args) {
        EventQueue.invokeLater(new GridTest()::display);
    }
}
