我正在使用 MDPI latex 模板这里。我有一张宽桌子，应该横跨整个宽度。
要重现此问题，请使用此 MWE。MWE 代码必须在 mdpi 模板内执行，例如 overleaf

我通常使用\begin{table*}并且它运行良好，我想知道引入新命令如specialtable、、parcol...的好处或目的是什么。
但表格仍然向右移动
请注意，在 IEEE 模板中，使用
\begin{table*}
....
\end{table*}
因此问题与 MDPI 内部命令有关，例如\specialtable

与此同时，模板也变得更好了；现在，“宽”图形只需放入环境中adjustwidth并使用\fulllength尺寸即可：
\begin{figure}
\begin{adjustwidth}{-\extralength}{0cm}
\centering
\includegraphics[width=.95\fulllength]{panoramic_figure}
\end{adjustwidth}
\caption{This figure will be full-page.\label{fig:panoramic}}
\end{figure}
原始答案（2021 年 12 月）
这里的问题是 MDPI 模板很奇怪。要插入宽图，您必须执行以下步骤（取自template.tex发行版中的文件）：
\end{paracol}
% Example of a figure that spans the whole page width (the commands \widefigure and \begin{paracol}{2}, \linenumbers, and\switchcolumn need to be present). The same concept works for tables, too.
\begin{figure}[H]
\widefigure
\includegraphics[width=15 cm]{Figs/circuit-2}
\caption{This is a wide figure with the full prototype.\label{fig:my-main-fig}}
\end{figure}
\begin{paracol}{2}
\linenumbers
\switchcolumn
...\end{paracol}等部分是强制的。模板\begin{paracol}{2}在\begin{document}命令中发出一个（您必须手动关闭由于图形太宽（在参考部分之前），因此要插入宽图形，您必须停止paracol，插入图形（手动定位），然后重新启动环境。
我想象，改变figure（table或specialtable，如模板中所建议的---测试它）然后放置一个tabularx跨越整体\linewidth将会给你想要的结果。
我本应以完全不同的方式组织模板。最后，它是一个单列模板，左侧有大量空白用于边距，当开始引用时，这些空白必须消失。这不是一个在 LaTeX 中容易复制的模板，但我认为 MDPI 使用的解决方案至少太脆弱了。

我猜，你喜欢获得这样的东西：
只是一些片段，如何设置你的表格。你的文档序言应该包含以下内容：
\usepackage{booktabs, makecell, tabularx}
\newcolumntype{L}{>{\raggedright\arraybackslash}X}
\usepackage{siunitx}
和表体：
%\caption{Summary of various datasets including free-view datasets, crowd-surveillance view and drone-view}
\label{table:table2}
\sisetup{group-minimum-digits=4,
group-separator={,},
}
\small
\setlength\tabcolsep{4pt}
\begin{tabularx}{\linewidth}{@{} l c L
S[table-format=4.0,product-symbol = {{\times}}]

您需要将此表代码片段插入到您的位置，即您的代码片段所在位置。如果您希望在表中使用 MWE，则首先需要在问题中提供一个 MWE，我们可以在 Overleaf 帐户中对其进行测试，而不仅仅是代码片段。

万一您来这里寻找如何在 MDPI LYX 模板中使用宽表，请不要忽视 lyx 中的命令：\widetable可以在 ERL 中将其用在表格开头以生成宽表。还有另一个命令 \widefigure 可以对图形执行相同操作，并且它在模板中使用。
