Inside a Generator method, can I access the data fetched?

Hi, I am writing a generator method for the table.Generator map. I have a database table called users and I wanted to show a Wrapper that listed each one of the Users on the current page (applying pagination) as a link. Something like this:

But inside the generator method, which I called GetAppsTable, can I get a list of the Users to be displayed to work with? I would need to loop over the rows obtained from the DB and fetch their name. Is this data already available anywhere, or do I have to make a new DB call to fetch it?
