我想用Java Swing中的JButtons做一个六角形的表格

import javax.swing.*;
import java.awt.*;

public class HexagonalGrid extends JFrame {
    private static final int SIZE = 5; // 表格大小
    private static final int BUTTON_SIZE = 60; // 按钮大小

    public HexagonalGrid() {
        setTitle("Hexagonal Grid");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setResizable(false);
        
        // 设置GridLayout为六角形布局
        setLayout(new GridLayout(SIZE, SIZE));

        // 创建按钮并设置为六边形
        for (int row = 0; row < SIZE; row++) {
            for (int col = 0; col < SIZE; col++) {
                if ((row + col) % 2 == 0) { // 通过奇偶性确定按钮显示颜色
                    JButton button = new JButton();
                    button.setPreferredSize(new Dimension(BUTTON_SIZE, BUTTON_SIZE));
                    button.setBackground(Color.YELLOW);
                    add(button);
                } else {
                    add(new JLabel()); // 空白标签用于填充空位
                }
            }
        }

        pack();
        setLocationRelativeTo(null);
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(() -> {
            new HexagonalGrid().setVisible(true);
        });
    }
}
