=SUM(COUNTIF(成绩!$D$96:$D$112,">="&{90,100})*{1,-1})公式里,&{90,100})*{1,
这个公式总体意思是：求“成绩”表内$D$96:$D$112区域成绩在90——100之间的人数!可是不理解里面的 &{90,100})*{1,-1}

公式的意思是：
D96:D112范围内大于等于90的个数乘1,大于等于100的个数乘-1,这两个乘积求和,公式应该这么来看：
= SUM( COUNTIF(成绩!$D$96:$D$112,">="&{90,100}) * {1,-1} )
它求的是：90

=SUM(COUNTIF(成绩!$D$96:$D$112,">="&{90,100})*{1,-1})公式里,&{90, COUNTIF($D$5:$D$8,$B4)=0,COUNTIF($D$5:$D$8,$B4)=1,COUNTIF($D =SUM(1/COUNTIF(F3:F31,F3:F31))如何在这个公式里加上两个条件, 如何理解excel数组公式 {=sum(1/countif(B8:K9,B8:K9))} =SUM(COUNTIF(K4:K33,{">=20",">30"})*{1,-1}) =SUM(COUNTIF(date!H:H,">"&{70,80})*{1,-1}) SUM(COUNTIF(K4:K33,{">=20",">30"})*{1,-1}) 是什么意思? =SUM(COUNTIF(date!H:H,">"&{70,80})*{1,-1}), =sum(1/countif(A1:A100,A1:A100)) =sum(1/countif(B8:K9,B8:K9)) SUM(IF(I:I="","",1/(COUNTIF(I:I,I: Excel =SUMPRODUCT((D$2:D$19>D2)*(1/(COUNTIF(D$2:D$19,D$2:D$1
