Tabular Caption?

You need to provide a table environment that encases the tabular environment as well as the \caption and \label statements.

% \documentclass statement and preamble
\begin{document}

\begin{table}
  \centering
  \begin{tabular}{|l|r|r|r|r|r|r|}
    % body of tabular environment 
  \end{tabular}
  \caption{This is my one big table} \label{tab:sometab}
\end{table}

\end{document}

P.S If you want to add the table inside your own .text file you don't need to use these:

\begin{document}

\end{document}
