使用 Google 表格中的数组公式滚动总和 [英] Rolling sum with array formula in Google Sheets

问题描述

我有下面的数据集.Col1 是给定的数据，Col2 是 Col1 前 5 行(含)的滚动和.

日期 Col1 Col201/04/20 2 202/04/20 1 303/04/20 4 704/04/20 705/04/20 706/04/20 5 1007/04/20 2 1108/04/20 709/04/20 710/04/20 1 811/04/20 312/04/20 113/04/20 114/04/20 115/04/20 1 1

有没有办法使用 arrayformula 来做到这一点，而不是在 Col2 向下的每个单元格中输入求和公式?

我有一个

I have the dataset below. Col1 is given data and Col2 is the rolling sum of the previous 5 rows of Col1 (inclusive).

Date      Col1  Col2
01/04/20  2     2
02/04/20  1     3 
03/04/20  4     7
04/04/20        7
05/04/20        7
06/04/20  5     10
07/04/20  2     11
08/04/20        7
09/04/20        7
10/04/20  1     8
11/04/20        3
12/04/20        1
13/04/20        1
14/04/20        1
15/04/20  1     1

Is there a way to use arrayformula to do this rather than inputting a sum formula into every cell in Col2 going down?

I had a similar question using count and was given this solution:

=ArrayFormula(filter(countifs(B2:B,">0",row(B2:B),"<="&row(B2:B),row(B2:B),">"&row(B2:B)-5),A2:A<>""))

Can I amend this to work for sum?

解决方案

You can also do it by the difference of two rolling sums if you wish:

=ArrayFormula(filter(sumif(row(B2:B),"<="&row(B2:B),B2:B)-sumif(row(B2:B),"<="&row(B2:B)-5,B2:B),A2:A<>""))
