如何在表格captionlabeltab2 The final MIMO scores of each model in two datasets 和begintabularccccc之间增加一个空行间距？begintableHrenewcommandarraystretch125centering Label your table accordinglysetlengthabovecaptio

要在表格的\caption和\begin{tabular}之间增加一个空行间距，可以在\caption下方添加一个空的\medskip命令。修改后的代码如下所示：

\begin{table}[H] \renewcommand\arraystretch{1.25} \centering % Label your table accordingly \setlength{\abovecaptionskip}{5pt} \caption{\label{tab2} The final MIMO scores of each model in two datasets} \medskip % 添加空行间距 \begin{tabular}{ccccc} \toprule[0.35mm] \multirow{2}{*}{\textbf{Models}} & \multicolumn{2}{c}{\textbf{Usability and comprehensiveness}}\cr \cmidrule0.25mm{2-3} \cmidrule0.25mm{4-5} & BTCV & AMOS 2022\ \midrule[0.15mm] U-Net & 0.128 & 0.238 \ V-Net & 0.615 & 0.664 \ nnU-Net & 0.513 & 0.830 \ Attention u-net & 0.705 & 0.679 \ Transunet & 0.346 & 0.757 \ Swin-unet & 0.295 & 0.340 \ Unetr & 0.564 & 0.372 \ Swin unetr & \bf{0.769} & \bf{0.851}\ \bottomrule[0.35mm] \end{tabular} \end{table}
