如何将下表单元格对齐到中间？

Question

我有下表，我想让它1出现在左列的中央。

\documentclass{article}

\begin{document}

\begin{tabular}{|l|p{1in}|}
\hline
1 & a b c d e f g h i j k l m n o p q r s t u v w x y z \\
\hline
\end{tabular}

\end{document}

我已经在 David 的解决方案（在对您的问题的评论中）中添加了宽度，\myw以使列的宽度与字符串的宽度完全相同1，如果您还有 2 位或 3 位数字，只需\settowidth{\myw}{...}在列定义中更改或放置您喜欢的任何宽度即可m{...}。

\documentclass{article}
\usepackage{array}
\newlength{\myw}
\settowidth{\myw}{1}

\begin{document}
    \noindent\emph{David's solution (with \textbackslash\texttt{array} package)}

    Note that both colums must have \texttt{m\{\dots\}} type.
    \begin{center}
    \begin{tabular}{|m{\myw}|m{1in}|}
        \hline
        1 & a b c d e f g h i j k l m n o p q r s t u v w x y z \\
        \hline
    \end{tabular}
    \end{center}

    \noindent\emph{Steven's solution (with no extra packages)}

    Note that it's necessary to explicity give the height of the \arraybackslash\texttt{parbox}. 
    Otherwise, the lines overlap the text.
    \begin{center}
    \begin{tabular}{|l|p{1in}|}
        \hline
        1 & \parbox[c][1.2\height]{1in}{a b c d e f g h i j k l m n o p q r s t u v w x y z}\\
        \hline
    \end{tabular}
    \end{center}
\end{document}
