一，效果形式：
二，导包：
\usepackage{diagbox}三，代码
\begin{table} \tiny
\centering \caption{The experimental results with different $A$ and $B$ values in Section \ref{spatial saliency} on FBMS database.}
\begin{tabular}{ | c | c | c | c | c | c | }
\hline \diagbox{$A$}{$B$} & 1 & 3 & 5 & 7 & 10 \\
\hline\hline AUC & 0.7738 & 0.7863 & 0.7934 &0.7887 &0.7882 \\
\hline\hline CC & 0.2607 & 0.2232 & 0.3160 &0.2198 &0.2524 \\
\hline\hline NSS & 0.0606 & 0.9652 & 1.2416 &1.0885 & 0.0936\\
\hline\end{tabular}\vspace{0cm}
\label{tab:parameter experiment 1}
\end{table}注：分成两份\diagbox{$A$}{$B$}，如果分成三份：\diagbox{$A$}{$B$}{$C$}
如把上面表格中的AUC也所在的表格分成三份A,B,C，则只需在对应代码部分换成\diagbox{$A$}{$B$}{$C$}, 完整如下：
\begin{table} \tiny
\centering \caption{The experimental results with different $\sigma_s$ values in Section \ref{spatial saliency} on FBMS database.}
\begin{tabular}{ | c | c | c | c | c | c | }
\hline \diagbox{$A$}{$B$} & 1 & 3 & 5 & 7 & 10 \\
\hline\hline \diagbox{$A$}{$B$}{$C$} & 0.7738 & 0.7863 & 0.7934 &0.7887 &0.7882 \\
\hline\hline CC & 0.2607 & 0.2232 & 0.3160 &0.2198 &0.2524 \\
\hline\hline NSS & 0.0606 & 0.9652 & 1.2416 &1.0885 & 0.0936\\
\hline\end{tabular}\vspace{0cm}
\label{tab:parameter experiment 1}
\end{table}效果如下：
