使用公式过滤数组(无VBA) [英] Filter an array using a formula (without VBA)

问题描述

是否可以使用单个公式(没有自动过滤器，VBA或其他列)过滤数组?

Is it possible to filter an array using a single formula (without autofilter, VBA, or additional columns)?

例如，我有以下电子表格:

For example, I have the following spreadsheet:

   A  | B     | C
 --------------------
1| ID | Class | Value
2| 1  | A     | V1
3| 1  | B     | V2
4| 2  | A     | V3
5| 3  | B     | V4
6| 3  | B     | V5

我想在VLOOKUP中使用此数组的子集.即，我只想与类为"B"的那些行匹配.所以我希望我可以使用类似以下的内容

I want to use a subset of this array in VLOOKUP. Namely, I only want to match against those rows where class is "B". So I was hoping I could use something like the following

=VLOOKUP(A3, FILTER_FUNC(A:C, B="B"), 3, false)

其中FILTER_FUNC是某种类型的函数或表达式，该函数或表达式返回仅包含满足条件的行的数组.

where FILTER_FUNC is some type of function or expression that returns an array that only contains those rows that meet the condition.

推荐答案

=VLOOKUP(A2,IF(B1:B3="B",A1:C3,""),1,FALSE)

Ctrl+Shift+Enter 进入.
