如果另一列中的前一行相同,则累积和
Cumulative Sum if previous row in another column is the same
我正在尝试做一些在 excel 中很简单的事情,但我需要将其添加到我的查询中。如果名称列等于前一行,我正在尝试在一列的新时间值列中创建累积和。下面的前后示例
数据输入Table
ID
Time
A
2
B
3
C
1
D
0.5
E
1
E
3
E
5
F
2
G
3
G
4
H
1
Table查询后
ID
Time
BeforeStart
A
2
0
B
3
0
C
1
0
D
0.5
0
E
1
0
E
3
1
E
5
4
F
2
0
G
3
0
G
4
3
H
1
0
基本上,如果列 ID 等于其上方的行,则将时间和其上方的 BeforeStart 行相加,否则为 0。
试试这个功能:
=IF(COUNTIF($A2:$A,$A2)=1,0,SUMPRODUCT((A2:$A=A2)*B2:$B)-B2)
在 power query 中,尝试下面并将表 2 替换为您的源数据的名称 table
let
xFunction = (xTable as table) as table => let
#"Added Index" = Table.AddIndexColumn(xTable, "Index", 1, 1, Int64.Type),
#"Added Custom" = Table.AddColumn(#"Added Index", "Running Total", each List.Sum(List.FirstN(#"Added Index"[Time],[Index]-1)))
in #"Added Custom",
Source = Excel.CurrentWorkbook(){[Name="Table2"]}[Content],
#"Changed Type" = Table.TransformColumnTypes(Source,{{"ID", type text}, {"Time", type number}}),
#"Grouped Rows" = Table.Group(#"Changed Type", {"ID"}, {{"data", each xFunction(_), type table }}),
#"Expanded data" = Table.ExpandTableColumn(#"Grouped Rows", "data", {"Time", "Running Total"}, {"Time", "Running Total"})
in #"Expanded data"
