Below is my M code, I am trying to add a column to show if List 1 match with anything in list 2. I am expecting the first line to be true and the last 2 to be false
Power Query:
let
Cities = Table.FromRows({{"New York", "Los Angeles", "Chicago", "Red", "Orange", "Yellow", "New York"},
{"Miami", "Houston", "Dallas", "Blue", "Purple", "Pink", "Brown"},
{"Phoenix", "Philadelphia", "San Antonio", "Black", "White", "Gray", "Turquoise"}}),
#"Added Custom" = Table.AddColumn(Cities, "Custom", each {[Column1],[Column2],[Column3]}),
#"Added Custom1" = Table.AddColumn(#"Added Custom", "Custom.1", each {[Column4],[Column5],[Column6],[Column7]}),
#"Removed Other Columns" = Table.SelectColumns(#"Added Custom1",{"Custom", "Custom.1"})
in
#"Removed Other Columns"
