![在表格标题前添加水平线](https://linux22.com/image/351844/%E5%9C%A8%E8%A1%A8%E6%A0%BC%E6%A0%87%E9%A2%98%E5%89%8D%E6%B7%BB%E5%8A%A0%E6%B0%B4%E5%B9%B3%E7%BA%BF.png)
我有一张表格,使用以下代码来生成:
\begin{table}[h!]
\centering
\hline\noalign{\smallskip}
%\vspace{-0.3cm}
\caption{ \textit{The percentages of all three cases of paired-end read alignments by HMMER and Short-Pair for the RNA-Seq data. ``HMMER w/o filtration" : running HMMER by turning off all filtration steps. ``HMMER GA cutoff": applying HMMER with gathering thresholds.}}
\label{tab:ArabThreeCases2}
%\vspace{-0.3cm}
\begin{tabular}{lllllll}
\hline\noalign{\smallskip}
Case& A, & B, & C, & D\\
& $E$-value 10 & w/o filtration, & GA cutoff &\\
& & $E$-value 10 & & \\
\noalign{\smallskip}
\hline
\noalign{\smallskip}
Case 1 & 34.51\% & 32.83\% & 22.51\% & 0.42\%\\
Case 2 & 28.42\% & 31.58\% & 8.84\% & 62.51\%\\
Case 3 & 37.07\% & 35.59\% & 68.65\% & 37.07\%\\
\hline
\end{tabular}{}
\end{table}
创建的表格在表格标题前有一条水平线,这正是我想要的。但如您所见,这条水平线的长度与表格中的其他水平线不同。我希望它们都具有相同的长度(标题上方线的长度)。我该如何实现?

像这样?
该表使用tabularx
环境与S
列类型的组合来表示带有数字的列:
\documentclass[12pt,a4paper,openright,oneside]{article}
\usepackage[font=small,
labelfont=bf,
textfont=it,
skip=1ex
]{caption}
\usepackage{booktabs, tabularx}
\newcommand\mc[1]{\multicolumn{1}{>{\centering\arraybackslash\hsize=1.1\hsize}X}{#1}}
\usepackage{siunitx}
\begin{document}
\begin{table}[h!]
\centering
\hrule height 1pt\smallskip
\caption{The percentages of all three cases of paired-end read alignments by HMMER and Short-Pair for the RNA-Seq data. ``HMMER w/o filtration" : running HMMER by turning off all filtration steps. ``HMMER GA cutoff": applying HMMER with gathering thresholds.}
\label{tab:ArabThreeCases2}
\begin{tabularx}{\linewidth}{>{\hsize=0.6\hsize}X
*{4}{S[table-format=2.2,
table-space-text-post=\,\%]<{\,\%}}
}
\toprule

Case 3 & 37.07 & 35.59 & 68.65 & 37.07 \cr

\end{tabularx}
\end{table}
