side by side tables
If two (or more) tables are to be placed side by side in LaTeX, there are several ways to do this. The main difference is whether the tables (tabular environment) should be placed inside or outside a table environment.
In case the tables are to be set in a table environment, the following options are available: First, you use the caption package. Or second, one uses the supcaption package
caption

\begin{document}
\begin{tabular}{ll}
\begin{tabular}{ccc}
A & B & C \\
\cline{1-3}
1 & 2 & 3 \\
\cline{1-3}
C & B & A \\

\cline{1-3}
