I've been using \hline for my horizontal lines in tabular, and \line(1,0){250} elsewhere.
I'm trying to automate some of the formatting for my tex documents, though, and it would be useful for me if I could draw a horizontal line across a page, no matter which context I'm in (whether I'm in tabular or not, for example). Is there a way to do this?
(I don't seem to be able to use \line, because of the width argument, so if there's a way to generate an appropriate number automatically there, that would work too)
