subfloat, how to put two tables side by side instead of one above the other?

Question

I need to put two tables side by side in my Springer LNCS paper. I used the \subfloat command but something went wrong: instead of being side by side, one is below the other.

Here's my code:

\documentclass[oribibl]{llncs}
\usepackage[numbers]{natbib}
\usepackage[pdftex,bookmarks=true]{hyperref}
\usepackage{amssymb}
\setcounter{tocdepth}{3}
\usepackage{graphicx}
\usepackage{url}
\usepackage{amsmath, amssymb}
\usepackage[table]{xcolor}
\usepackage[lofdepth,lotdepth]{subfig}


\def\truncationLevel{k}
\def\AP{\mathtt{AP}}
\def\NAC{\mathtt{NAC}}
\def\AC{\mathtt{AC}}
\def\AR{\mathtt{AR}}
\def\ROC{\mathtt{ROC}}
\def\AUC{\mathtt{AUC}}


\begin{document}

Do you have any idea about solving this problem? How could I put the two tables side by side?
