Answer 1

如果列E的值如下所示，则可以使用SUMIF公式仅对列A求和：

=SUMIF(E:E,"w",A:A)

Answer 2

You are looking for something like =SUMPRODUCT(--(NOT(E1:E5="W")),A1:A5) . Sumproduct multiplies everything in one column with everything in another, and sums the results. -- converts a boolean statement into a 1 or a 0.

So, with this formula, you would be multiplying each item in column A with either a 1 or a 0. Obviously, things multiplied by zero do not have any effect on the final sum :)
