SUM(COUNTIF(A1:N8,">"&{10,15}*{1,-1})) 如何理解{1,-1}的意思?
SUM(COUNTIF(A1:N8,">"&{10,15}*{1,-1})) 如何理解{1,-1}的意思?
SUM(COUNTIF(A1:N8,">"&{10,15}*{1,-1})) 如何理解{1,-1}的意思?
{10,15}*{1,-1}={10,-15}
就是统计A1:N8这个区域中大于10的个数和大于-15的个数之和
例如你的A1到A4单元格分别为1,2,3,11
=SUM(COUNTIF(A1:A4,">"&{10,15}*{1,-1}))
结果为5
大于10的1个,大于-15的4个
SUM(COUNTIF(A1:N8,>&{10,15}*{1,-1})) 如何理解{1,-1}的意思?
=SUMPRODUCT(1/COUNTIF(A1:A20,A1:A20)) 与=sum(1/COUNTIF(A1:A20,A1:A20)) 区别?写明要点哦.
COUNTIF(A1:D30,A1:
countif（a1:b2,a1:
excel 谁能详细解释一下数组函数=SUM(1/COUNTIF(A1:A15,A1:A15))的意思!
{=SUM(IF(A1:F3,1/COUNTIF(A1:F3,A1:F3)))} 请解释一下该数组公式是如何得出的范围内数值种类数目
=sum(1/countif(A1:A100,A1:A100))公式中countif前的“1/”怎么理解?=INT(SUM(1/IF(COUNTIF($B$2:$B$14,IF($A$2:$A$14=F2,$B$2:$B$14,))=0,1000,(COUNTIF($B$2:$B$14,IF($A$2:$A$14=F2,$B$2:$B$14,))))))公式中的=0,1000怎么理解?
sum(1/COUNTIF(range,criteria))是什么意思
=COUNTIF(A1:A10,A)+COUNTIF(A1:A10,E)+COUNTIF(A1:A10,F) 求简化
=sum(1/countif(B8:K9,B8:K9))
=SUM(COUNTIF(date!H:H,>&{70,80})*{1,-1}),
=SUM(COUNTIF(K4:K33,{>=20,>30})*{1,-1})
SUM(IF(I:I=,,1/(COUNTIF(I:I,I:
SUM(COUNTIF(K4:K33,{>=20,>30})*{1,-1}) 是什么意思?
COUNTIF(A$1:A1,A1)=1和COUNTIF(A:A,A1),期待您的回复.
=IF(COUNTIF(A$1:A1,A1)=1,COUNTIF(A:A,A1),)
EXCEL {=SUMPRODUCT(1/COUNTIF(A1:A7,A1:A7))}
=IF(SUM(A1:A5)>0,SUM(A1:A5)
