一切似乎都运行良好，代码运行除了计算错误。
程序错误地打印了联赛的最终排名。
应该有18场比赛，因此每支球队应该打18场比赛。
总积分计算如下：胜=3分，平=1分，负=0分。
净胜球的计算方式为：进球数-失球数。
进球数是球队在整个赛季的进球数。
失球数是一支球队整个赛季失球数。
赢得的比赛是一支球队在整个赛季中赢得的比赛数量。
输掉的比赛是球队整个赛季输掉的比赛数量。
平局数是一支球队整个赛季平局的比赛数。
我还希望在每个比赛日回合结束时根据之前的比赛日结果打印并显示最终表格，然后用户才能开始输入下一个比赛日回合的结果
当我运行程序时，它错误地打印了决赛桌，我不知道如何根据之前的比赛日结果在每轮比赛后打印决赛桌。
