所以这就是我想要做的:
1) Look-up A2 value in Column C.
2) The rows in Column C where A:2 value exists, then the respective cell in D will get the value
of B. If it does not exists then D will have a value of 0.
the formula im using in D2 is something like =LOOKUP(A2,C:C,REPLACE WITH B) and if not exists then b2 = 0
我可以使用匹配但不知道如何用正确的值替换
