我有以下 MWE，它有一个长表（为清楚起见，仅显示一部分）。我想更改字体大小，同时保留标题大小。MWE 1 会更改字体和标题大小，如图所示。为了更改表格条目字体大小，我尝试了 MWE 2，但它会出错，无法按预期工作。如何在不影响标题大小的情况下更改表格条目字体大小？

- 要使标题字体的大小与表格中使用的字体大小无关，请使用包
caption（如建议的那样约翰·科米洛在他的评论中） - 为了使表格适合文本宽度，可以
\tabcolsep相应减少，如果您喜欢减小表格中的字体大小，\small可以这样做

好吧，对于定义表格和图形的标题，使用 caption 包是很常见的。在那里，您可以通过 \captionsetup 正确设置标题定义。
\usepackage{caption}[2016/02/21]
\captionsetup{
labelsep=period, %Sets a point
%format=hang,
labelfont=bf,
textfont=bf,
font=large %Large font for example
}
编辑：如果您尝试将表格调整到页面大小，则不必寻找合适的字体大小。您可以使用 \resizebox width 调整实际页面大小。例如：
\begin{table}[htb]
\center
\caption{My Table Caption}
\label{tab:NewTable}
\resizebox{\pagewidth}{!}{%
\input{ExternTable}
}
\end{table}
