Array Help
Hi everyone. I'm trying to make a basic 4x3 table. How do I do this?

Hmm. Double-click this:

$\begin{tabular}{c|c|c}
1 &3 &7\\ \hline
3 &6 &0
\end{tabular}$

The {c|c|c} part is an argument to the tabular environment telling LaTeX that you want three centered columns (you could use l or r for left or right justified, although I'm not sure how well that's translating in MHF.), and that you want single vertical lines in-between the columns. The \hline command gives you a horizontal line in-between the two lines. Compare:

$\begin{tabular}{|l|c|r|}
1+x &3-x^{2}-\sqrt{y} &7+\ln(r\theta)\\
3+y+z &6 &0
\end{tabular}$

Hope this helps.
