"",符号的功能？

kitty123

=IF(C6="","",IF(OR(C6={"椿木","杂木","白杨木","松木","榉木","白橡木","橡胶木","椿木毛料","白杨木毛料","松木毛料","橡胶木毛料","桦木","桦木毛料","枫木","进口松木","橡木","水曲柳","枫木毛料","桐木","松木拼板","曲木","橡胶木拼板"},F6=""),"",((D6+3)*(E6+3)*G6)/0.87/(2440*1220)))

次公式中为什么OR()后面有"",符号的呀，就是((D6+3)*(E6+3)*G6)/0.87/(2440*1220))) 前为什么要用"",符号的呀，如果我把"",去掉的话，此公式为就显示为FALSE的呀，这是什么的呀？

"" 是的空的意思。

先判断单元格是否有内容，无：C6=""，返回：""（即空白）,
