Table visualization and case sensitivity

Happy New Years Day! 

Add custom column, not conditional column.

Conditional Column options are too basic to handle List.Contains or invisible characters.

Then paste into the custom column window:

if List.Contains(List.Transform({97..122}, each Character.FromNumber(_)), Text.Start([DATABASE_NAME], 1)) then Character.FromNumber(8236) else ""

I'm assuming your column is named [DATABASE_NAME], but if not, then substitute the right name.

Basically...
List.Contains({a..z}, "e" is true.
List.Contains({a..z}, "E" is false.
