It's gonna be a bit tricky, methinks. Take a look at the \cline tag,
which allows you to draw a horizontal line across a range of specified
columns. So instead of \hline at the end of every line you put
\cline{2-6}. That'll get you the right horizontal lines. As for the
verticals, you'll have to start messing with multicolumns, AFAIK.


It might look something like...

\def\st#1\multicolumn{1}{c|}{#1}
\begin{tabular}{ccccc}
	& A	&A	&...	\\ \cline{2-5}

\st{C}	&\st{1}	&\st{1}	&...	\\ \cline{2-5}
\st{C}	&\st{1}	&\st{1}	&...	\\ \cline{2-5}
	& B	& B	&...	\\

\end{tabular}

Don't quote me on this ;) It's late and I don't know where my LaTeX
book is.
