=IF(SUM(IF(MOD(COLUMN(I3:BQ3)-1,2)=0,I3:BQ3))=0,"",SUM(IF(MOD(COLUMN(I3:BQ3)-1,2)=0,I3:BQ3)))意思?
=IF(SUM(IF(MOD(COLUMN(I3:BQ3)-1,2)=0,I3:BQ3))=0,
SUM(IF(MOD(COLUMN(I3:BQ3)-1,2)=0,I3:BQ3))的意思是求I3:BQ3中奇数列的数字和,即从I3开始,隔一列加一个.
如果SUM(IF(MOD(COLUMN(I3:BQ3)-1,2)=0,I3:BQ3))的结果为0,公式就返回空字符（即什么都不显示）,否则就显示合计的结果.
MOD(COLUMN(I3:BQ3)-1,2)=0,等同于MOD(COLUMN(I3:BQ3),2)=1,也可以去掉后边的=1.
“=SUM(IF($I$3:$I$22>I3,1/COUNTIF($I$3:$I$22,$I$3:$I$22)))+1” =IF(SUM(A1:A5)>0,SUM(A1:A5) excel中:=SUM(IF(MID(A1,COLUMN(A1:E1),1)="a",1,0))怎么解释 K3=IF(J3=0,0,ROUND(I3/J3,2)) IF函数:=IF(MOD(单号,2)0,1,0) =IF(SUM(C1:D1)0,SUM(D1:I1)/SUM(C1:D1)*100,0) 烦请知者具体讲解 劳烦赐教 =SUM(OFFSET($F16:$F45,0,(COLUMN(A1)-1)*2)) =IF(SUM($G$5:$G$33)=0,0,G14/SUM($G$5:$G$33)) =IF(A3"",SUM(B$2:B2)-SUM(C$1:C1),"") 看不懂 row()-1 =IF(ROW()>SUM(IF($B$2:$B$10=$E$2,1,0))+1,"",INDEX($C EXCEL中公式 =SUM(IF(A3=$A$2:$A$1421,1,0)) 麻烦EXCEL,=IF((DE372-(CA372-CQ372))>=0,AF372,IF((DE372-(SUM(OF
