Power Query: Unique values in both columns

Hello all!

 

I have a doubt regarding Power Query.

 

I have 2 columns, with duplicates. I want to keep only those that are unique in both. For instance:

If I remove duplicates from column1, I only want to remove if they stay unique in column2.

I.e, if I remove row 1 I can't remove row 3 otherwise I would have two "11".

 

I hope my explanation made sense.

 

Thanks in advance.

Use below Query to achieve this output

let
    Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
    #"Added Index" = Table.AddIndexColumn(Source, "Index", 0, 1, Int64.Type),
    #"Inserted Modulo" = Table.AddColumn(#"Added Index", "Modulo", each Number.Mod([Index], 4), type number),
    #"Filtered Rows" = Table.SelectRows(#"Inserted Modulo", each ([Modulo] = 0 or [Modulo] = 3)),
    #"Removed Columns" = Table.RemoveColumns(#"Filtered Rows",{"Index", "Modulo"})
in
    #"Removed Columns"

  

To achieve the below output, replace [Modulo] = 0 or [Modulo] = 3 in 5th row of the code above

with [Modulo] = 1 or [Modulo] = 2

Updated code is below

let
    Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
    #"Added Index" = Table.AddIndexColumn(Source, "Index", 0, 1, Int64.Type),
    #"Inserted Modulo" = Table.AddColumn(#"Added Index", "Modulo", each Number.Mod([Index], 4), type number),
    #"Filtered Rows" = Table.SelectRows(#"Inserted Modulo", each [Modulo] = 1 or [Modulo] = 2),
    #"Removed Columns" = Table.RemoveColumns(#"Filtered Rows",{"Index", "Modulo"})
in
    #"Removed Columns"
