Hey danielboi ,

 

create a custom column using an if statement in combination with the function Text.Contains (https://docs.microsoft.com/en-us/powerquery-m/text-contains) like so

if
Text.Contains( [Column1] , "A")
and
( 
Text.Contains( [Column2] , "yellow") or Text.Contains( [Column2] , "red")
)
then "omit" else "keep"

Be aware of the brackets.

Then you can use to values to filter the table and remove the column after the filtering.

Hopefully, this provides an idea on how to tackle your challenge.

Regards,
Tom

Hey danielboi ,

if you are familiar with M and the Advanced Editor you can use this one:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclTSUSpKTVGK1YGwK1NzcvLL4dz0otTUPKXYWAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Column1 = _t, Column2 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Column1", type text}, {"Column2", type text}}),


    #"onego" = 
    Table.SelectRows (
        #"Changed Type" , (_) => 
    
         ( Text.Contains( [Column1] , "A") and 
( Text.Contains( [Column2] , "yellow") or Text.Contains( [Column2] , "red") ) = false 
)
    )


//     #"Added Custom" = Table.AddColumn(#"Changed Type", "condition", each if Text.Contains( [Column1] , "A") and 
// ( Text.Contains( [Column2] , "yellow") or Text.Contains( [Column2] , "red") 
// ) then "omit" else "keep")
in
    #"onego"

Tom
