Excel formula 嵌套IF语句中的参数太多

在excel中，我使用嵌套的IF语句，不确定为什么这个函数中有太多的参数。是否因为陈述中存在重叠

嵌套的IF语句应该输出以下选项之一：HazOp、SIL、LOPA、HazOp&SIL、HazOp&LOPA

=IF(AND(C42="HazOp"),"HazOp",IF(AND(C43="SIL"),"SIL"),IF(AND(C44="LOPA"),"LOPA",IF(AND(C42="HazOp",C43="SIL"),"HazOp & SIL",IF(AND(C42="HazOp",C44="LOPA"),"HazOp & LOPA",0))))

如果您有Office 365 Excel，请使用以下选项：

=TEXTJOIN(" & ",TRUE,C42:C44)

=MID(IF(C42<>""," & " & C42,"") & IF(C43<>""," & " & C43,"") & IF(C44<>""," & " & C44,""),4,99)

如果没有，请使用：

=TEXTJOIN(" & ",TRUE,C42:C44)

=MID(IF(C42<>""," & " & C42,"") & IF(C43<>""," & " & C43,"") & IF(C44<>""," & " & C44,""),4,99)

如果只传递1个参数，为什么要使用AND函数？试试这个IFC42=HazOp，HazOp，IFC43=IFL，IFL，IFC44=LOPA，LOPA，IFANDC42=HazOp，C43=IFL，HazOp&IFL，IFANDC42=HazOp，C44=LOPA，HazOp&LOPA，0如果C42=HazOp，C43=IFL，C44=LOPA，会是空的吗，或者单元格中还有其他值吗？@Scott Craner如果没有这些单元格，它们可能是空的W Idk您可以这样做，非常感谢：
