我真的厌倦了搜索。这在 MS-Word 中是一个非常简单的问题，但我无法在 Latex 中运行它。我有一个两列文档。如果表格的宽度足够，则没有问题，但如果表格的宽度小于列宽（无论是一列还是两列），我会使用它，{adjustbox}{width=1\textwidth}但它会改变字体的大小。例如对于以下代码：
\section{RESULTS}\label{sec:res}One hundred patients enrolled in this study including 63 (63\%) men and 37 (37\%) women.

然后我有：
我曾经使用过{width=0.5\textwidth}，如果我将 0.5 改为 1，表格会变得更大。有人能告诉我如何才能让表格适合列宽吗？
提前感谢您的支持。

通过使用\adjustbox，您基本上可以保证某种主要字体大小的改变。请改用tabular*环境。
哦，为了获得间距适当的水平线，请加载booktabs包及其宏\toprule、\midrule和\bottomrule。

\section{Results}\label{sec:res}
One hundred patients enrolled in this study including 63 (63\%) men and 37
(37\%) women. Mean age of participants was $60 \pm 5$ years with minimum
age of 44 years old and maximum age of 80 years old. Patients' demographics
are summarized in Table~\ref{table1}.
\begin{table}[ht]

\begin{tabular*}{\columnwidth}{@{\extracolsep{\fill}}lr@{}}

\end{table}
The minimum and maximum of measured peak SBP before CR, was 90 and
155 mmHg respectively. The mean of peak SBP was $121.95 \pm 14.21$
mmHg. The minimum and maximum of measured SBP after CR, was 100 mmHg
and 150 mmHg respectively with mean of $121.55 \pm 11.84$ mmHg. Mean
of SBP did not significantly change after CR ($P = 0.76$). The
minimum of measured DBP before CR was 60 mmHg and the maximum was
90 mmHg with mean of $78.55 \pm 7.18$ mmHg. The minimum of measured DBP
after CR was 60 mmHg and maximum was 90 mmHg. The mean DBP was $77.35
\pm 7.08$ mmHg. Mean of DBP was not significantly different before and
after CR (P = 0.12) Minimum of PPI before CR was 0.33 and maximum of it
was 0.83 with mean of $0.35 \pm 0.046$. After CR, minimum of PPI was
0.27 and maximum was 0.53 with mean of $0.36 \pm 0.048$. Mean of PPI
was not significantly different before and after CR ($P = 0.12$).
