Convert rows from same customer into extra columns using PowerQuery

[BobKoenen]

HI all, 

I am trying to do the opositie from a normal Pivot in Power Query but I cannot get it working. Hope you can help me. 

My data looks like this. 

Customer Number	Atribute A	Atribute B	Atribute C
1	Bottle	Spike	Horse
1	Cap	Triangle	Moose
1	Water	Round	Duck

 And I need it to look like this:

Customernr	A	B	C	A1	B1	C1	A2	B2	C2
1	Bottle	Spike	Horse	Cap	Triangle	Moose	Water	Round	Duck

My Table contains multiple Customers and a customer can have up to 10 rows which need to be converted into columns. (A10 B10 C10. I Hope you can help me fix this. 

Thanx in advance

@amitchandak 
Thankx a lot for replying. Unfortunatly I cannot use an index column because my data is a big table which has more than one customernumber 

CustomerNumer	A	B	C
1111	Value A	Value B	Value C
1111	Value A	Value B	Value C
1112	Value A	Value B	Value C
1113	Value A	Value B	Value C
1113	Value A	Value B	Value C
1113	Value A	Value B	Value C

Is there a way to use the index to count the number of rows from the same customer? Maybe that wil fix it.

@BobKoenen , Try this in power Query

let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUXLKLynJSQUyggsys0G0R35RcapSrA5E2jmxAEiGFGUm5qWDlfnm5yNJhyeWpBYB6aD80rwUIO1SmpytFBsLAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"Customer Number" = _t, #"Atribute A" = _t, #"Atribute B" = _t, #"Atribute C" = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Customer Number", Int64.Type}, {"Atribute A", type text}, {"Atribute B", type text}, {"Atribute C", type text}}),
#"Added Index" = Table.AddIndexColumn(#"Changed Type", "Index", 1, 1, Int64.Type),
#"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Added Index", {"Customer Number", "Index"}, "Attribute", "Value"),
#"Merged Columns" = Table.CombineColumns(Table.TransformColumnTypes(#"Unpivoted Other Columns", {{"Index", type text}}, "en-US"),{"Attribute", "Index"},Combiner.CombineTextByDelimiter(" ", QuoteStyle.None),"Merged"),
#"Pivoted Column" = Table.Pivot(#"Merged Columns", List.Distinct(#"Merged Columns"[Merged]), "Merged", "Value", List.Max)
in
#"Pivoted Column"
