采用 IEEE 系统期刊格式；
我正在尝试插入一个很宽的表格/图形，因此它将占据一整列。
\documentclass[lettersize,journal]{IEEEtran}
\usepackage{tabularx}
\usepackage{lipsum,graphicx}
\begin{document}
\lipsum[1-7]
\onecolumn
\begin{tabularx}{\textwidth}{|X|X|X|X|}
\hline
\multicolumn{4}{|c|}{\textcolor{red}{\textbf{LUL }}} \\
\hline
\centering\arraybackslash Title & \centering\arraybackslash Overview & \centering\arraybackslash Advantage(s) & \centering\arraybackslash Disadvantage(s) \\
\hline
Duis leo. & Sed fringilla mauris sit amet nibh. Donec sodales sagittis magna & Sed fringilla mauris sit amet nibh. Donec sodales sagittis magna & Sed fringilla mauris sit amet nibh. Donec sodales sagittis magna \\ \hline

\end{tabularx}
\twocolumn
\lipsum[1-2]
\end{document}
但是，使用 \onecolumn 开关后再使用 \twocolumn 开关会导致以下问题；
图表/表格留下了很多空间，如附图中我突出显示的红色圆圈所示，这不利于展示，我的导师也不接受。我有什么办法可以填补这个空白吗？
最好是通过接下来的文本后表格/图表？
答案1
\onecolumn和\twocolumn是强制分页符，因此如果使用它们，您必须“手动”移动文本。这就是 LaTeX 提供浮动表格的原因。
