我看到了很多针对这个特定问题的答案。但是，是否可以将一列文本拆分成单独的行，例如在环境中tabularx添加换行符mulitcolumntabular
到目前为止我的表格是这样的：
\begin{table}[!htbp] \centering
\caption{Means of the key variable}
\label{}
\small
\begin{tabular}{@{\extracolsep{1pt}} D{.}{.}{-3} D{.}{.}{-3} D{.}{.}{-3} D{.}{.}{-3} D{.}{.}{-3} D{.}{.}{-3} D{.}{.}{-3} D{.}{.}{-3} D{.}{.}{-3} }

当然我会接受解决方案，tabularx但由于我从未使用过它，因此如果可能的话我建议留在该tabular环境中。

我建议使用 、 和 来提出这种变siunitx体eqparbox解决makecell方案collcell：
\documentclass{article}
\usepackage{booktabs, ragged2e, eqparbox}
\usepackage{siunitx, collcell, makecell}
\newcommand{\range}[1]{\eqparbox{ra}{#1}}
\newcolumntype{R}{>{\collectcell\range}c<{\endcollectcell}}

答案2
我不明白为什么每个表格单元格都被包裹在\multicolumn{1}{c}{...}包装器中。
D我会 (a)根据每列数字的特征定制列类型的参数，以及 (b) 使用tabularx环境允许在表格的标题单元格中换行。
您可能想要考虑一个比“学校年限变化”更短的标题。
