Power Query - How to number each column 1 to n

[Sam7]

Hello, 

How do I number each row of data 1 to 5?  I want each row to be numbered, with no grouping etc.  I just want the sequence of numbering done. 

Thanks

Hi

Add index column, transform column modulo 5 and add 1

let
Source = YourSource,
Index = Table.AddIndexColumn(Source, "Index", 0, 1, Int64.Type),
#"Modulo5+1" = Table.TransformColumns(Index, {{"Index", each Number.Mod(_, 5)+1, Int64.Type}})
in
#"Modulo5+1"
