[texhax] aligning array columns at bottom rather than top vertically

[Steve Schwartz]

Johan,

Have you tried using \phantom (which typesets its argument and makes a
box to hold the result, but just puts the blank box in the output)?
There's also \vphantom to make a phantom vertical strut and \hphantom to
make the equivalent horizontal space., e.g.,

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\documentclass{article}
\begin{document}
Hello

$$
\begin{array}{ll}
\phantom{premise} & premise \\ ---- & ------ \\ something & else 
\end{array}
$$

Wasn't that easy?
\end{document}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

An alternative is \usepackage{array} which allows you to specify the
vertical as well as horizontal alignment in a tabular environment. You
could then use m alignment to middle align (vertically) the row
containing your rules.
