将文本放在由三部分组成的表格的一行中间

Question

我正在尝试将一些文本放在仅跨越表格一部分的水平线中间。以下是我目前的表格

\documentclass{article}
\usepackage{amssymb, amsmath, bm}
\usepackage[flushleft]{threeparttable}

\begin{document}

\begin{table}[H]
\caption{\textbf{Filtered errors}}
\label{table:summary_statistics}
\begin{threeparttable}
\footnotesize
\renewcommand{\TPTminimum}{\linewidth}
\makebox[\linewidth]{%
\begin{tabular}{lccccccccc}
\toprule
\hline

\thead{Maturity \\} & \thead[l]{Mean \\ }   & \thead{Std. dev. \\ } &  & 
\thead[l]{Mean \\ }   & \thead{Std. dev. \\ } &  &  \thead[l]{Mean \\ }   & 
\thead{Std. dev. \\ } \\
\midrule

12     & 3.617 & 2.635 & & 0.099 & 9.658 & & 0.993 & 0.863 \\
24     & 3.874 & 2.611 & & 0.188 & 9.566 & & 0.991 & 0.877 \\

60     & 4.511 & 2.398 & & 0.627 & 9.317 & & 0.988 & 0.891 \\
84     & 4.837 & 2.285 & & 1.007 & 9.406 & & 0.987 & 0.892 \\
120    & 5.195 & 2.174 & & 1.498 & 9.642 & & 0.986 & 0.890 \\
Median & 1.910 & 1.205 & & -0.616& 4.376 & & 0.966 & 0.442 \\
Mean   & -0.731& 0.900 & & -2.691& 1.634 & & 0.949 & 0.596 \\      
#Lower \\ 
\bottomrule
\end{tabular}
}
\begin{tablenotes}\footnotesize
 \item Note: This table reports \par 
\end{tablenotes}
\end{threeparttable}
\end{table}

\end{document}

我还将表格的截图放在下面。

如何将文本（例如 DNS/MS-DNS/MS-DRA）显示在行中间而不是左侧？

先感谢您。

Answer 1

\thead对于手头的表格来说，这种机制似乎有点过度了。我建议使用\multicolumn{2}{c}{...}指令来代替居中标题单元格，以及 而\cmidrule不是\cline。

我还建议将数字与各自的小数点对齐，并在数学模式下排版，以便使用印刷上适当的数学减号符号而不是文本模式破折号来表示负数。

然而，请不要将\footnotesize其用作主表，除非您想故意惹恼您的读者。

就在这里。我使用 、 和siunitx改进booktabs了 布局。正如 @Mico 在他的评论中所建议的那样，表格没有必要适合边距，而应该在环境中进行编码。tabularxcaption\footnotesize\captionthreeparttable
