I have the following code to layout two tables side by side:
\begin{minipage}{0.3\textwidth}
\begin{tabular}{c | c | c | c | c | c | c}
F & D & E & G & P & A & L\\
\hline
C & H & I & I & U & G & F\\
\hline
G & Z & G & A & F & Z & U\\
\hline
F & R & \textbf{H} & \textbf{A} & \textbf{U} & \textbf{S} & Z\\
\hline
R & P & L & I & N & F & H\\
\hline
L & U & G & I & A & C & T\\
\hline
A & B & D & N & E & R & Z\\
\end{tabular}
\end{minipage}
\begin{minipage}{0.3\textwidth}
\begin{tabular}{c | c | c | c | c | c | c}
F & D & E & G & P & A & L\\
\hline
C & H & I & I & U & G & F\\
\hline
G & Z & G & A & F & Z & U\\
\hline
F & R & \textbf{H} & \textbf{A} & \textbf{U} & \textbf{S} & Z\\
\hline
R & P & L & I & N & F & H\\
\hline
L & U & G & I & A & C & T\\
\hline
A & B & D & N & E & R & Z\\
\end{tabular}
\end{minipage}
But it doesn't work. The tables are one below the other. What am I doing wrong?

minipageenvironments are superfluous. – egreg Nov 23 '11 at 10:45
