[edit] LaTeX tables

I (may have) answered your question over at the Reference Desk. -Splash 19:44, 19 August 2005 (UTC)

Hi there. Yes, I think you haven't told LaTeX to \usepackage{amsmath} which introduces most of the mathematical commands, and is the package that, in this case at least, the stretchy brace is taken from. Here is a compiling, full document that just produces the table you mentioned. You should be able to copy-paste this into a blank .tex file and have it compile:
\documentclass{report}
\usepackage{amsmath}
\begin{document}
\begin{table}
\centering
\begin{tabular}{r|c|c}
Input & Output & Formula\\
\hline
A & 1 & $x=f_1(y)$\\
B & 2 & $x=f_2(y)$\\
$\left\{\begin{matrix} \mathrm{C} \\ \mathrm{D} \\ \mathrm{E} \end{matrix} \right.$ & 3 & $x=f_3(y)$ \\
F & 4 & $x=f_4(y)$
\end{tabular}
\end{table}
\end{document}

If you plan to do much that is clever with mathematics, you'll find things like \usepackage{amsfonts} and \usepackage{amssymb} useful too. Hope that helps. -Splash 21:08, 20 August 2005 (UTC)
