Data transformation help

[JS]

Hello all experts. 

I have the data below

I would like to transform it into

Is there anyway that this can be achieved?

Hi JS,

You can do that like this

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMtQ11DUyMLRQ0lEyMgETBgYGSrGxAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t, Column3 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type date}, {"Column2", Int64.Type}, {"Column3", Int64.Type}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "List", each List.Range({0..[Column2]},1)),
    #"Expanded List" = Table.ExpandListColumn(#"Added Custom", "List"),
    #"Added Custom1" = Table.AddColumn(#"Expanded List", "Custom", each [Column3]/[Column2]),
    #"Added Custom2" = Table.AddColumn(#"Added Custom1", "Custom.1", each Date.AddMonths([Column1], [List]-1))
in
    #"Added Custom2"

The Source is just the table I have create to hold the data example
