Hi,
Here is my plain issue :
i've got a 2 column dataset
Lib Nb_Pad
Pad1 1
Pad2 2
Pad10 10
Pad5 5
I've seen that using the formula Text.PadStart
it was possible to do something like this :
Pad_Lib
Pad1
Pad2
Pad10
Pad5
The thing is i'm not good enough to set that up in M. -:)
I think of something like :
-------- M -------
let
Source = Excel.Workbook(File.Contents("MyPath\Myfile.xlsx"), null, true),
Order_Sheet = Source{[Item="Order",Kind="Sheet"]}[Data],
Promote = Table.PromoteHeaders(Order_Sheet, [PromoteAllScalars=true]),
// insert a step here that will do the pading trick !!
Pad = Table.TransformColumns(Promote, {{"Lib", each Text.Padstart("Lib", "Nb_Pad"), type text}})
in
Pad
-------------
Thanks for your help !
