给定一个数组，我如何索引匹配每个值并在没有帮助列的情况下对它们求和？

Question

I have multiple rows 34 columns wide with a reference Designator(RefDes) in each one that correlates to a value. I am trying to find a way to match each RefDes to its value and sum those together without the use of a helper cell for each column to give each row a total value.

My current formula will work with a helper cell but that adds 34 more columns and makes it very messy and hard to read.

=INDEX(FullFlow2[[Category Times]:[Category Times]],MATCH(N4,FullFlow2[[REFDES]:[REFDES]]))

Followed by a =sumproduct() in another column to collect the values.

Not sure if this is something I will need to use VBA for or if I can make it work without it.

This is the RefDesTable below

This is the FullFlow2 Table below

Answer 1

Use SUMIFS wrapped in a SUMPRODUCT:

=SUMPRODUCT(SUMIFS(FullFlow2[[Category Times]:[Category Times]],FullFlow2[[REFDES]:[REFDES]],YourFirstTableName[1st]))

Replace YourFirstTableName with the correct name for the table.
