【问题描述】：

是否可以为条件列的 1 行/输出组合 2 个值？下面是一个例子。

当前，2 行：

each if 
[source] = "Source" and [medium] = "Medium" and [medium-2] = "Paid Search" 
or [source] = "Source" and [medium] = "Medium" and [medium-2] = "cpc"
then ="Paid Search"

Desired, 1 Line - 将“medium-2”的两个值合并为 1 行：

each if
[source] = "Source" and [medium] = "Medium" and [medium-2] = "Paid Search" or "cpc"
then ="Paid Search"

感谢您的帮助，斯科特

【解决方案1】：

逻辑上，

([source] = "Source" and [medium] = "Medium" and [medium-2] = "Paid Search") or
([source] = "Source" and [medium] = "Medium" and [medium-2] = "cpc")

等价于

[source] = "Source" and [medium] = "Medium" and
( [medium-2] = "Paid Search" or [medium-2] = "cpc" )

即

( A && B && C ) || ( A && B && D ) = ( A && B ) && ( C || D )

如果问题与语法更相关，那么我会指出

[medium-2] = "Paid Search" or [medium-2] = "cpc"

可以改写为

List.Contains( { "Paid Search", "cpc" }, [medium-2] )

除非您有两个以上的选择，否则不会更短。

就是这样！！谢谢。
