I am trying to split the "Score\exp" cell diagonally where I can write "score" in one half and "exp" in the other half, any ideas?
My code:
\begin{table}[htbp]
\centering
\caption{Add caption}
\begin{tabular}{rrrrrrrr}
\toprule
Score\textbackslash{}exp & 1 & 2 & 3 & 4 & 5 & 6 & 7 \\
\midrule
1 & 1 & 2 & 3 & 4 & 5 & 6 & 7 \\
2 & 2 & 2 & 2 & 2 & 2 & 2 & 2 \\
3 & 3 & 3 & 3 & 3 & 3 & 3 & 3 \\
4 & 4 & 4 & 4 & 4 & 4 & 4 & 4 \\
5 & 5 & 5 & 5 & 5 & 5 & 5 & 5 \\
6 & 6 & 6 & 6 & 6 & 6 & 6 & 6 \\
7 & 7 & 7 & 7 & 7 & 7 & 7 & 7 \\
8 & 8 & 8 & 8 & 8 & 8 & 8 & 8 \\
9 & 9 & 9 & 9 & 9 & 9 & 9 & 9 \\
10 & 10 & 10 & 10 & 10 & 10 & 10 & 10 \\
11 & 11 & 11 & 11 & 11 & 11 & 11 & 11 \\
12 & 12 & 12 & 12 & 12 & 12 & 12 & 12 \\
13 & 13 & 13 & 13 & 13 & 13 & 13 & 13 \\
\bottomrule
\end{tabular}%

\end{table}%
