Not that i am aware of. The normal input mode is rich text and of course you’re free to simply type tags inline, but they will not automatically get any special formatting or functionality. I prefer to make a column for them which is formatted differently than my main entry (“Topic” is the default column for a row in OO).
One advantage of having a tags type for a column is to get autocomplete, but this can be solved in other ways if you like to maintain an independent tags list system-wide (i.e. using a text expander, Alfred, etc. to do completion/insertion from this list).
