Overlay Two Tabel

Hello - instead of looping through columns, I think it would be better to append the tables, unpivot, transform and repivot, like this:

let
    Source = Table.Combine({Table1, Table2}),
    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(Source, {"Name", "Place"}, "Attribute", "Value"),
    #"Replaced Value" = Table.ReplaceValue(#"Unpivoted Other Columns","",null,Replacer.ReplaceValue,{"Value"}),
    #"Grouped Rows" = Table.Group(#"Replaced Value", {"Name", "Place", "Attribute"}, {{"Data", each _, type table [Name=nullable text, Place=nullable text, Attribute=text, Value=text]}}),
    #"Added Custom" = Table.AddColumn(#"Grouped Rows", "Custom", each if List.NonNullCount ( [Data][Value] ) > 1 then Text.Combine ( List.Sort ( [Data] [Value] ), " - " ) else List.RemoveNulls ( [Data][Value] ){0} ),
    #"Removed Columns" = Table.RemoveColumns(#"Added Custom",{"Data"}),
    #"Pivoted Column" = Table.Pivot(#"Removed Columns", List.Distinct(#"Removed Columns"[Attribute]), "Attribute", "Custom")
in
    #"Pivoted Column"

Result
