# Put a text on the left top corner of a tabular

I have several tabular as follows in my article. To save some space, I don't want Step 2 to occupy a whole line, maybe just putting it on the left top corner of the tabular is a good idea...

Does anyone know how to realize it?

\documentclass[runningheads,orivec]{llncs}
\usepackage{calc}% http://ctan.org/pkg/calc
\usepackage{mathtools}
\usepackage{array}
\newcolumntype{C}[1]{>{\centering\arraybackslash$}p{#1}<{$}}
\begin{document}
\noindent Step 2:
\begin{center}
\begin{tabular}{lllll}
&$\begin{array}{C{\widthof{$0$}}|*{3}{C{\widthof{$-2$}}}} & i & 0\\ \hline i & 0 & 0 \\ 0 & 0 & 0\\ \end{array}$ \quad
&$\left(\begin{array}{C{\widthof{$0$}}|*{2}{C{\widthof{$-7$}}}|*{2}{C{\widthof{$-7$}}}} & x & \multicolumn{1}{c}{y} & i & 0 \\ \hline x & 0 & \multicolumn{1}{c}{} & 0 & 0 \\ y & & \multicolumn{1}{c}{0} & & \\ \cline{4-5} i & 0 & & 0 &0\\ 0 & 0 & & 0 & 0 \end{array}\quad,\text{int}\right)$ \quad \quad

\end{tabular}
\end{center}
