    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Changed Type", {"column1"}, "Attribute", "Value"),
    Custom1 = Table.Split(#"Unpivoted Other Columns",3),
    Custom2 = List.Transform(Custom1,each Table.ToRows(Table.Pivot(_,List.Distinct([Attribute]),"Attribute","Value")){0}),
    Custom3 = Table.FromRows(Custom2)
