这段代码是一个名为GameBoard的类，用于绘制一个游戏板。它有几个方法：

1. __init__方法是类的构造函数，它接受cell_width、margin、n和screen等参数，并初始化成员变量。它还调用draw_board和draw_buttons方法来绘制游戏板和按钮。

2. draw_board方法用于绘制游戏板的网格线。

3. draw_buttons方法用于绘制游戏板上的按钮，包括QUIT和Restart。

4. draw_first_chess方法用于绘制首个棋子。

5. drawchess方法用于根据给定的行、列和颜色绘制棋子。

6. draw_now_chess方法用于绘制当前棋子。

7. draw_box方法用于绘制一个红色边框的文本框。

该类使用了pygame库来进行绘图操作。
