is meant for giving the transliteration. If nothing is given, then it tries to create a default transliteration if that is available for the language. suppresses that. Quite often, using  as some parameter in a template means "disable the default" although it depends on which template.

As for the width, you can also arrange the table the other way, like the Dutch table. You probably don't need separate rows/columns for the short and long forms either, compare the Slovene template where these are also combined (but in the Dutch one they are separate).
