Create a table with double title

I have this code to create a table, but I want to create a table like the image below. How can I modify the code to create the table?

\begin{tabular}{|l|l|l|l|l|}
\hline
   & AB & A & B & O \\ \hline
AB & 0  & 1 & 1 & 2 \\ \hline
A  & 1  & 0 & 2 & 2 \\ \hline
B  & 1  & 2 & 0 & 2 \\ \hline
O  & 3  & 3 & 3 & 0 \\ \hline
\end{tabular}
\end{table}

Solution

  • Hopefully easy:

    \documentclass{article}
\usepackage{multirow}

\begin{document}

\begin{table}
\centering
\begin{tabular}{cc|c|c|c|c|}
 & \multicolumn{1}{c}{ } & \multicolumn{4}{c}{Classified As} \\
 &                       & AB & A & B & O \\ \cline{2-6}
\multirow{4}{11mm}{True Blood Type} %
 & AB                    & 0  & 1 & 1 & 2 \\ \cline{2-6}
 & A                     & 1  & 0 & 2 & 2 \\ \cline{2-6}
 & B                     & 1  & 2 & 0 & 2 \\ \cline{2-6}
 & O                     & 3  & 3 & 3 & 0 \\ \cline{2-6}
\end{tabular}
\end{table}

\end{document}

    The above MWE outputs the following table:

    This first sketch can then be improved aesthetically in several ways!
