按列对 Google 表格中每一行的最小值求和

Question

I would like to write the formula that sums for each column the values that are the minimum for each row.

I have a table like this:

	A	B	C
1	10	20	5
2	3	4	9
3	1	7	4
Sum of only min	4	0	5

In the example, column A has 3 and 1 that are the minimum of row 2 and 3.

Answer 1

You can try with this formula:

    =BYCOL(
MAP(A2:4,LAMBDA(e,IF(e=MIN(INDEX(A1:4,ROW(e))),e,IF(COUNTA(INDEX(A2:4,,COLUMN(e)))=0,"",0)))),
LAMBDA(each,IFERROR(SUM(each))))

Answer 2

Here's another solution:

=ArrayFormula(BYCOL(IF(A1:C3=BYROW(A1:C3,LAMBDA(r,MIN(r))),A1:C3),LAMBDA(c,SUM(c))))
