=SUMIF(OFFSET($B$1,1,FREQUENCY($4:$4,$F2)),G$1,$D$2)-SUM(G$1

excel里面 =SUM(($A$2:$A$15=$F2)*($B$2:$B$15=G$1)*$D$2:$D$15)是什 =SUMIF(BM!$C$2:OFFSET(BM!$C$2,0,$B$2-1),OFFSET(BM!$C$2,0,$B$ SUM(OFFSET($D$1,(ROW()-1)*2,2)) =SUM(OFFSET($F16:$F45,0,(COLUMN(A1)-1)*2)) offset函数有这样的一个公式,B15=SUM(OFFSET($B$1,MATCH(A15,A2:A11.0),3)) 这公式可以简写不?=SUM(SUMIF('1'!A:A,A5,'1'!B:B),SUMIF('2'!A:A,A5,'2' =SUM(OFFSET(B21,0,0,1,COUNTA(OFFSET(B34,0,0,1,30)))) =SUM(SUMIF(表1!A:A,{4,5,6},表1!B:B))在用这个公式的时候是相当于循环了三次吗? =SUM(OFFSET(A1,E2,MATCH(G2&"总计",B1:C1,0),F2-E2+1)) 我想问下E2在这起 吉他这个调啥意思 Open G Tuning 1=D 2=B 3=G 4=D 5=G 6=D 现有可逆反应：2A(g)+3B(g)=可逆=nC(g)+4D(g).(1)起始时,将amolA和bmolB充入固定容积的 1.已知A(g) +B(g)=C(g) △H1; D(g) + B(g) =E(g) △H2 .若1 mol A和D的混
