我使用以下代码创建了一个表：
\documentclass[12 pt,Times New Roman] {article}
\usepackage[utf8]{inputenc}
\usepackage { amsmath }
\usepackage{setspace}
\setstretch{1.5}
\usepackage{hyperref}
\usepackage[toc,page]{appendix}
\usepackage[a4paper,lmargin={2.5cm},rmargin={2.5cm},
tmargin={2.5cm},bmargin = {2.5cm}]{geometry}
\usepackage{caption}
\usepackage{booktabs}
\usepackage{fancyhdr}
\pagestyle{fancy}
\lhead{}
\chead{}
\rhead{Page \thepage}
\lfoot{}
\cfoot{}
\rfoot{}
\sloppy
\begin{document}
\begin{table}[h!]
\selectfont\centering
\caption[Caption]{Caption}
\begin{tabular}{p{1cm} p{1cm} p{1cm} p{1cm} p{1cm} c c c c c}
\hline\hline
& title & title & title & title \\
\hline
A & 1.2 & 2.3 & 5.6\sym{**} & 4 \\
& (5.06) & (5.56) & (3.42) & (0.59) \\
[1em]
B & -9.87\sym{*} & -9.63\sym{*} & 0.58 & 1.98\sym{***}\\
& (5.07) & (5.66) & (3.58) & (0.59) \\
\hline
Adjusted \(R^{2}\) & ... & ... & ... & ... \\
\hline\hline
\multicolumn{5}{l}{\footnotesize Robust standard errors in parentheses, \sym{*} \(p<0.10\), \sym{**} \(p<0.05\), \sym{***} \(p<0.01\)}\\
\multicolumn{5}{p{\ylength}}{\footnotesize note note note}\\
\\
\end{tabular}
\end{table}
\end{document}
问题是表格的宽度与文本的宽度相同，因此行的线条太长。如能得到任何帮助，我们将不胜感激。

考虑上述评论并猜测你的表格应该是什么样子：
\documentclass[12pt] {article}
\usepackage[a4paper,margin=2.5cm]{geometry}
\usepackage[utf8]{inputenc}
\usepackage {amsmath}
\usepackage{setspace}
\setstretch{1.5}
\usepackage{caption}
\usepackage{calc}
\usepackage{booktabs,tabularx}
\newlength\mylength
\setlength\mylength{0.5\textwidth}
\newcommand\mcp[1]{\multicolumn{5}{p{\mylength-2\tabcolsep}}{\footnotesize #1}}
\usepackage{showframe}
\renewcommand*\ShowFrameColor{\color{red}}
\begin{document}
\begin{table}[htb]
\centering
\setlength\tabcolsep{4pt}
\caption[Caption]{Caption}
\label{my table}
\begin{tabularx}{\mylength}{l X X X X}
\toprule
& title & title & title & title \\
\midrule
A & 1.2 & 2.3 & 5.6{**} & 4 \\
& (5.06) & (5.56) & (3.42) & (0.59) \\ [1em]
B & -9.87{*} & -9.63{*} & 0.58 & 1.98{***} \\
& (5.07) & (5.66) & (3.58) & (0.59) \\
\midrule
Adjusted \(R^{2}\)
& ... & ... & ... & ... \\
\midrule
\mcp{Robust standard errors in parentheses,
{*} \(p<0.10\), {**} \(p<0.05\), {***} \(p<0.01\)} \\
\mcp{note note note} \\
\bottomrule
\end{tabularx}
\end{table}
\end{document}
如果猜测错误，请编辑您的问题并澄清您的问题。

使用，您可以在表格下方添加表格注释，{NiceTabular}其nicematrix宽度等于表格本身的宽度。
在下面的代码中，键tabularnote在表格注释区域中添加了一些数据。表格注释本身由内置命令插入\tabularnote。请注意，当多个表格注释具有完全相同的内容时，该内容只会在表格注释区域中插入一次。
\documentclass{article}
\usepackage{geometry}
\usepackage{caption}
\usepackage{nicematrix,enumitem,booktabs}
\ExplSyntaxOn
\NewDocumentCommand { \stars } { m } { \prg_replicate:nn { \value { #1 } } { $\star$ } }
\ExplSyntaxOff
\begin{document}
\begin{table}
\centering
\caption{Caption}
\NiceMatrixOptions{notes/para,notes/bottomrule,notes/style=\stars{#1}}
\begin{NiceTabular}{lllll}% <--- The % is mandatory
[tabularnote = The robust standard errors in are presented in parentheses.]
\toprule
& title & title & title & title \\
\midrule
A & 1.2 & 2.3 & 5.6\tabularnote{$p<0.05$} & 4 \\
& (5.06) & (5.56) & (3.42) & (0.59) \\[1em]
B & -9.87\tabularnote{$p<0.10$} & -9.63\tabularnote{$p<0.10$} & 0.58 & 1.98\tabularnote{$p<0.01$} \\
& (5.07) & (5.66) & (3.58) & (0.59) \\
\midrule
Adjusted \(R^{2}\)
& ... & ... & ... & ... \\
\midrule
\end{NiceTabular}
\end{table}
\end{document}
