Python井字棋界面行显示异常求助：需实现指定格式输出

当前程序界面仅以空格分隔棋盘格子，无行列分隔线，无法清晰区分每个格子；期望实现的界面是每个格子用竖线分隔，每行之间用横线分隔，行列编号与棋盘格子一一对应。

修改方案 #

核心是重写show_board方法调整棋盘输出格式，同时修正顶部的行列提示：

                break
        if win:
            return win
        return False

    def is_board_filled(self):
        for row in self.board:
            for item in row:

                print('---|---|---')

    def start(self):
        self.create_board()

        player = 'X' if self.get_random_first_player() == 1 else 'O'

            print("---|---|---")
            
            self.show_board()

            # 获取用户输入
            row, col = list(
                map(int, input("输入行号和列号（用空格分隔）: ").split()))
            print()

        # 显示最终棋盘
        print()
        self.show_board()

# 启动游戏
tic_tac_toe = TicTacToe()
tic_tac_toe.start()

修改说明 #

1. show_board方法：使用' | '.join(row)将每行的格子用竖线连接，同时在除最后一行外的每行下方打印---|---|---作为行分隔线，实现清晰的棋盘格子区分。
2. start方法：将顶部的行列提示从1 2 3和-----修改为1 | 2 | 3和---|---|---，与棋盘格式保持一致，让用户更直观地对应行列号。
