latex：三线表

1. revtex4-1 这个模版里面貌似无法用booktabs包。三线表格，得用其自带的ruledtabular。下面是一个例子：
   

\begin{table}[t]
\begin{ruledtabular}
\begin{tabular}{cccccccc}
\multirow{2}*{} & \multicolumn{3}{c}{GGA} & \multicolumn{3}{c}{mBJ} & \multirow{2}*{Ideal Weyl
} \\
\cline{2-4}\cline{5-7}
& $k_x^\ast=k_y^\ast(\AA^{-1})$ & $k_z^\ast(\AA^{-1})$ & $\%$ of $1/a$ & $k_x^\ast=k_y^\ast(\AA^{-1})$ & $~~k_z^\ast(\AA^{-1})~~$ & $\%$ of $1/a$ &  \\
\colrule
  $\text{CuTlSe}_2$ & 0.0061 &0.0695 & 1.2 & 0.0069 & 0.0589 & 1.4 & Y \\
  $\text{CuTlTe}_2$ & 0.0202 &0.0576 & 4.0 & 0.0115 & 0.0483 & 2.2 & N \\
 
\end{tabular}
\end{ruledtabular}
\end{table}
