我有一张这样的桌子：
我想要的是这样的：
或者
使用我的表格代码可以做到这一点吗？

听起来像是这个包的工作multirow：
\documentclass{article}
\usepackage{multirow}
\begin{document}
\begin{table}
\centering
\setlength{\tabcolsep}{7pt}
\renewcommand{\arraystretch}{1.5}
\begin{tabular}{| p{.20\textwidth} | p{.70\textwidth} | }
\hline
\textbf{Priority} & \textbf{To-do} \\ \hline
\multirow{4}{*}{\textbf{Very high}} & \textbf{Requirements}\\ \cline{2-2}
& xxxxxxxxxxxxxxxxxxxxxxxxxxxxx \\ \cline{2-2}
& xxxxxxxxxxxxxxxxxxxxxxxxxxxxx \\ \cline{2-2}
& xxxxxxxxxxxxxxxxxxxxxxxxxxxxx \\ \hline
\end{tabular}
\caption{To-do-list}
\end{table}
\end{document}
[我用 代替，\begin{center}...\end{center}因为\centering前者增加了额外的间距。
