Certain number of index values for dynamic number of rows

[CrazyFrog]

Hello,

I am currently trying to implement the following: I have given the following table with a dynamic number of scenarios and their corresponding AddValue values. 

Now I am trying to insert indices from 0 to 15 for each scenario (see screenshots from excel example):

I am grateful for any help. Thanks in advance!

Hi CrazyFrog,

An approach is to,

1. Add a column "Index" containing a list 0-15 for each row.
2. Expand the list to rows.

Here is example code,

let
  Source = Excel.CurrentWorkbook(){[Name="tbl"]}[Content],
  #"Added Index List" = Table.AddColumn(Source, "Index", each List.Numbers(0,16,1)),
  #"Expanded Index List" = Table.ExpandListColumn(#"Added Index List", "Index"),
  #"Changed Type" = Table.TransformColumnTypes(#"Expanded Index List",{{"Index", Int64.Type}, {"Add Value", Int64.Type}, {"Scenario", Int64.Type}})
in
  #"Changed Type"

yielding,
