[texhax] tables question

[M.N.A.Smadi]

hi;
am using this code to make a table. It is show as a table but latex is 
not doing the line wrapping in a good way.  The line goes the end of the 
pages without ever line wrapping.

\begin{table}[hang]
\centering
\caption{SIP Responses}
\begin{tabular}{|l|l||}
    \hline
\textbf{\bf Class Code}  & {\bf Function}                \\
    \hline \hline
xx       &  
whatevenrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr 
   \\

    \hline
\end{tabular}    
\label{tab:sip_responses}
\end{table}

any ideas on how to make it wrap?

thanks
