我想控制表格的宽度。有什么办法可以解决这个问题吗？
\begin{table}[b]
\centering
\caption{The results of Human motion recognition [$\%$].}
\arrayrulecolor{black}
\begin{tabular}{lc!{\color{black}\vrule}lc}
\toprule
\multicolumn{2}{c!{\color{black}\vrule}}{Weizmann dataset} & \multicolumn{2}{c}{KTH dataset} \\
\multicolumn{1}{c}{Methods} & Accuracy [\%]~ & \multicolumn{1}{c}{Methods} & Accuracy [\%] \\
\arrayrulecolor{black}\hline
Fathi et al. \cite{Fathi2008ActionRB} & 90.00 & Schuldt et al. \cite{Schldt2004RecognizingHA} & 71.70 \\

答案1
为了使表格适合列内，我建议您在第 2 列和第 4 列标题中的“准确度”和“[%]”之间提供一个换行符。顺便说一句，我认为没有必要在表格中间设置规则。
