# Multirow table help

I am trying to build a table like this in Latex but I am new to this program and, even though I have read many blogs, I cannot understand how to build a table like this Thank you in advance for your time

your question is for sure duplicate ... but now I'm to lazy to find the same question here ;-). So, an example of use of multirow package is:

\documentclass{article}
\usepackage{multirow}

\begin{document}
\begin{tabular}{|*{6}{l|} }
\hline
&   & aaaa & bbbb & cccc & dddd \\
\hline
\multirow{3}{*}{LR}
& 1 &   &   &   &   \\  \cline{2-6}
& 2 &   &   &   &   \\  \cline{2-6}
& 2 &   &   &   &   \\
\hline
\multirow{3}{*}{SV}
& 1 &   &   &   &   \\  \cline{2-6}
& 2 &   &   &   &   \\  \cline{2-6}
& 2 &   &   &   &   \\
\hline
\end{tabular}
\end{document}
