The probably simplest way with tabular: use | for vertical lines and \hline for horizontal lines.
\documentclass{article}
\begin{document}
\begin{tabular}{c|c|c}
1 & 2 & 3 \\ \hline
4 & 5 & 6 \\ \hline
7 & 8 & 9
\end{tabular}
\end{document}

For more complex drawings, I would use TikZ. The TikZ example gallery provides many code examples for a start.
