如何在 Latex 中的表格中添加说明文字

Question

我想创建一个包含解释性文字的表格，如下图所示：

这是我写的代码：

\begin{table}[]
\caption{N-best examples from the MSCOCO test set. Bold lines indicate a
novel sentence not present in the training set.}
\label{table3}
\centering
\resizebox{.90\columnwidth}{!}{%
\begin{tabular}{@{}l@{}}
\toprule
A man throwing a frisbee in a park                         \\
\textbf{A man throwing a frisbee in a park}                \\
\textbf{A man standing in the grass with a frisbee.}       \\
A close up of a sandwich on a plate.                       \\
A close up of a plate of food with french fries.           \\
A white plate topped with a cut in half sandwich.          \\
A display case filled with lots of donuts.                 \\
\textbf{A display case filled with lots of cakes.}         \\
\textbf{A bakery display case filled with lots of donuts.} \\ \bottomrule
\end{tabular}%
}
\end{table}

我如何才能获取此表中的底线？我试过了\threeparttable，但似乎会产生错误。有人能演示如何做到这一点吗？

由于缺乏有关您的文档的任何信息，我只能为您的表格编写以下代码：

编辑： 在我的测试平台上，我添加了相关的包并形成了一个 MWE，任何人都可以测试所提出的解决方案。

\documentclass{article}
\usepackage[labelfont=up,labelsep=newline, skip=1ex]{caption}
    \begin{table}[ht]
\centering
    \begin{threeparttable}
\caption{N-best examples from the MSCOCO test set.}
\label{table3}
\begin{tabular}{@{}l@{}}
    \toprule
A man throwing a frisbee in a park                         \\
\textbf{A man throwing a frisbee in a park}                \\
\textbf{A man standing in the grass with a frisbee.}       \\
A close up of a sandwich on a plate.                       \\
A close up of a plate of food with french fries.           \\
A white plate topped with a cut in half sandwich.          \\
A display case filled with lots of donuts.                 \\
\textbf{A display case filled with lots of cakes.}         \\
\textbf{A bakery display case filled with lots of donuts.} \\ 
    \bottomrule
\end{tabular}
\begin{tablenotes}[para, flushleft]\itshape
Bold Lines Indicate a Novel Setence not Present in the Training set
\end{tablenotes}
    \end{threeparttable}
    \end{table}
\end{document}

使用我的测试平台得到的结果为：

这就是你要找的吗？
