Did you try making a plus column using the formula provided? It does what you want. Obviously you'd then use it in place of the native column you're using now -- unless you wanted both columns. Substring(data_column,start_character,total_characters) is equivalent to Right(data_column,total_characters) -- it starts from the left at start_character and outputs total_characters. "Right" outputs total characters starting from the right.
I don't know of any trim command on the list options tab page. There is a "Mid" option that lets you specify: "starting character, total characters" that would accomplish the same thing as the Substring function used in a plus column formula, and in fact, uses "Substring" when the backend is MS-SQL.
