调整多行列的长度而不进行嵌套

Question

如何允许多行列自动扩展以适合换行的文本段落（而无需嵌套其他列）？我正在尝试寻找一种比在相邻列中添加人工空间更优雅的解决方案，因为第一列中的文本在不同版本中的长度会有所不同。

\documentclass{article}

\usepackage{index}
\usepackage{array}
\usepackage{multirow}
\usepackage{multicol}
\begin{document}


\begin{table}[]
\centering
\begin{tabular}{|p{4cm}|cc|}
\hline
\multirow{3}{4cm}{This is a long paragraph of important information that should not spill over into the cell below, but as you can see, it is indeed spilling.} 
                        & \multicolumn{1}{c|}{\multirow{2}{*}{xxx}} & xxx \\ \cline{3-3} 
                        & \multicolumn{1}{c|}{}                     & xxx \\ \cline{2-3} 
                        & \multicolumn{2}{c|}{xxx}                        \\ \hline
\end{tabular}
\end{table}

\end{document}

Answer 1

这实际上超出了 的合理范围multirow。正如另一个答案所示，有时您可以解决它，但它需要一些猜测，并且在更复杂的情况下会变得太难。

更好的解决方案是使用tabularray包；它就是为此而设计的。

\documentclass{article}

\usepackage{index}
\usepackage{array}
\usepackage{tabularray}
\usepackage{multirow}
\begin{document}

\begin{table}
\centering
\begin{tblr}{|p{4cm}|c|c|}
\hline
\SetCell[r=3]{l}{This is a long paragraph of important information that should not spill over into the cell below, but as you can see, it is indeed spilling.} 
                        & \SetCell[r=2]{c}{xxx} & xxx \\ \cline{3-3} 
                        &                       & xxx \\ \cline{2-3} 
                        & \SetCell[c=2]{c}{xxx} &                       \\ \hline
\end{tblr}
\end{table}

\end{document}

Answer 2

使用垂直扩展单元格\renewcommand{\arraystretch}{<factor>}

\documentclass{article}
    
\usepackage{multirow}

\begin{document}    

\begin{table}[htp!]
    \centering
        \renewcommand{\arraystretch}{2.3} % added <<<<<<<<<<
    \begin{tabular}{|p{4cm}|cc|}
        \hline
        \multirow{3}{4cm}{This is a long paragraph of important information that should not spill over into the cell below, but as you can see, it is indeed spilling.} 
        & \multicolumn{1}{c|}{\multirow{2}{*}{xxx}} & xxx \\ \cline{3-3} 
        & \multicolumn{1}{c|}{}                     & xxx \\ \cline{2-3} 
        & \multicolumn{2}{c|}{xxx}                        \\ \hline
    \end{tabular}
\end{table}
    
\end{document}
