在计数中只出现两次？你试过什么了吗？只有当只有两个延迟原因存在时，解决方案才会起作用#Ba、b或c的延迟原因可能发生在我的意思是a的任何地方；b#c或b#a#c、 c#b#a、 然后你问了一个不清楚的问题，样本数据没有反映出真正的问题是什么。更新您的问题。聪明的解决方案+1Hi以上解决方案不起作用。如果我们有“Los NE abc；#Angeles；#California”之类的值，请创建一个摆弄您的实际数据并粘贴链接，我会看一看。不，我不会再更新我的答案！您已将问题更改了三次，因此让用户要求他们不断更新是不公平的。只有当只有两个延迟原因存在时，解决方案才会起作用#Ba、b或c的延迟原因可能发生在我的意思是a的任何地方；b#c或b#a#c、 c#b#a、 然后你问了一个不清楚的问题，样本数据没有反映出真正的问题是什么。更新您的问题。聪明的解决方案+1Hi以上解决方案不起作用。如果我们有“Los NE abc；#Angeles；#California”之类的值，请创建一个摆弄您的实际数据并粘贴链接，我会看一看。不，我不会再更新我的答案！您更改了三次问题，让用户不断更新是不公平的。
