[英]Google Sheets : horizontal (row) conditional Arrayformula
I have row 1 containing some dates (undetermined number, because end formula will be a dynamic number) and I want row 5 to display the average of every column that has a date as a header.我的第 1 行包含一些日期(未确定的数字,因为最终公式将是一个动态数字),我希望第 5 行显示日期为 header 的每一列的平均值。
Trying to have this array formula work:试图让这个数组公式起作用:
arrayformula(iferror(
if(B1:1 = "",,
AVERAGE(
indirect(
SUBSTITUTE(ADDRESS(1,COLUMN(B1:1),4),"1","")
& 7 & ":" &
SUBSTITUTE(ADDRESS(1,COLUMN(B1:1),4),"1","")
)))))
I think I did isolate the problem in the arrayformula, I can't see where the problem lies with it?我想我确实在 arrayformula 中隔离了问题,我看不出问题出在哪里?
and here's the link to the spreadsheet:这是电子表格的链接:

QUERY
method: QUERY
方法:=ArrayFormula(IF(B1:1="",,IFERROR(VLOOKUP(COLUMN(B1:1),QUERY(SPLIT(FLATTEN(TRANSPOSE(COLUMN(B7:7)&"♦"&B7:1000)),"♦"),"select Col1,avg(Col2) where Col2 is not null group by Col1 label avg(Col2) ''",0),2,FALSE),)))
MMULT
method: MMULT
方法:=ArrayFormula(IF(B1:1="",,IFERROR(MMULT(N(TRANSPOSE(ROW(B7:1000)^0)),N(B7:1000))/MMULT(N(TRANSPOSE(ROW(B7:1000)^0)),N(B7:1000<>"")),)))
