问题
I have a Google Spreadsheet of numbers. How do I take the maximum value from each column, and summarize them using only one formula? (No temp cells, no scripts.)
1 2 1
0 1 3
0 2 0
For the table above the result should be 6 (1+2+3, the maximum value of each column). But I'd like a solution that works for much larger tables, too.
As a more general question, I'd like to find out how I could fold 2D ranges into 1D arrays using an arbitrary operator (like MAX and SUM in this case).
回答1:
Assuming your data in range A2:D, to get the maximum of every row (array output) try
=query(transpose(query(if(row(A2:D)>=transpose(row(A2:D)),transpose( A2:D)),"select max(Col1),max(Col2),max(Col3),max(Col4) ",0)),"Select Col2", 0)
If you need to process a lot of columns, this may be better
=ArrayFormula(QUERY(TRANSPOSE(QUERY(TRANSPOSE( A2:D) , "Select "&"MAX(Col"&JOIN( ", MAX(Col",ROW(INDIRECT( "YY1:YY"&ROWS(A2:A)))&")"))), "Select Col2", 0))
To sum, just wrap SUM() around the above formulas.
回答2:
MAX by columns in A1:C3
=INDEX(QUERY({A1:C3},"Select "&"MAX(Col"&JOIN(", MAX(Col",SEQUENCE(COLUMNS(A1:C3))&")"),0),2)
MAX by rows in A1:C3
=TRANSPOSE(INDEX(QUERY(TRANSPOSE(A1:C3),"Select "&"MAX(Col"&JOIN(", MAX(Col",SEQUENCE(ROWS(A1:C3))&")"),0),2))
Substitute MAX with MIN to get the minimums.
