看起来这个问题已经被问过很多次了，但由于我对乳胶还不熟悉，所以我无法解决我的问题。
我的 .tex 文档中有以下 longtable

我只是想确保“肌肉基础”列中的文本不会超出我的页边距。“肌肉基础”列下的每一行文本可以有多行，但在同一行中。
答案1
\newcolumntype这可以通过使用命令为最后一列定义列说明符并使用一个列宽参数来实现，如下所示。
\newcolumntype{C}[1]{>{\raggedright \arraybackslash\hspace{0pt}}m{#1}}
表示m{#1}段落列的文本垂直对齐在中间（需要array包）
C{7cm}人们可以通过例如防止碰到页边距来决定最后一列的宽度。
