Add a column with a list of Values

[rmeng]

Can you help me with power query to add a column with a list of values into a table:

Hello @rmeng 

you can add a list as a formula for your new column. Afterwards expand the list to new rows. Here an example of a list for your new column (you can also reference a column of another query here like MyOtherQuery[List]

{"Name", "etc"}

 here the complete code

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUXJUitWJVjICspzALGMgy1kpNhYA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [ID = _t, Name = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"ID", Int64.Type}, {"Name", type text}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each {"Name", "etc"}),
    #"Expanded Custom" = Table.ExpandListColumn(#"Added Custom", "Custom")
in
    #"Expanded Custom"

it transforms this

into this

Copy paste this code to the advanced editor in a new blank query to see how the solution works.

@rmeng Use a Merge query in Power Query Editor and I believe it looks like you want a Full Outer Join.

But I don´t have any comun ID between the List and the other table?
