将表格放入 \t​​wocolumn 文档中，并将标题水平居中

tag-icon • tag-icon horizontal-alignment captions multicolumn multicol justification
将表格放入 \t​​wocolumn 文档中，并将标题水平居中

我正在使用\twocolumn文档，但是我想在列中间添加一个表格。我尝试使用\onecolumn，但它将图形或表格放在下一页，使整个页面都占满了\onecolumn。

我看到使用\multicols可以解决问题。问题是，无论我如何设置，最终的表格标题都不会居中，而且我仍然无法获得overful hbox error有关表格内容的信息。

\section{Introduction}
The following report analyzes the mission \textbf{New Horizons} mission to Pluto and its insights. This report is based on the experience from Dr. Alan Stern, principal investigator of the New Horizons mission and the Chief Scientist at Moon Express \cite{stern2018chasing}.

NASA's New Horizons spacecraft is the first spacecraft to explore Pluto up close, flying by the dwarf planet and its moons on July 14, 2015. In early 2019, New Horizons flew past its second major science target—2014 MU69, the most distant object ever explored up close \cite{nasa_new_horizons}.

让我们来解决您的问题中出现的各种问题。

（1）IEEEtran for journal 将生成一份两列文档。无需其他软件包。

（2）该类允许使用更宽的表格table*。（其风格是两侧没有垂直线）

（3）宽表将转到下一页。说明建议使用该dblfloatfix包使两列浮​​动元素按正确顺序显示出来。

（4）表格的标题应放在表格的顶部。

（5）要将标题放在页面中央，请将其放在 \parbox{\textwidth}{\caption{ ....}}

（6）请勿使用， \resizebox{因为它会改变表格的字体大小（脚注大小）。

我认为你能做的最好的事情就是给班级一个选项onecolumn，并使用它multicol来使文​​本变成双列，并将表格放在其中两列之间。

\documentclass[journal, a4paper, 11pt, onecolumn]{IEEEtran}
....
\usepackage{multicol}
....
\begin{multicols}{2}
\section{Introduction}
The following report analyzes the mission \textbf{New Horizons} mission to Pluto and its insights. This report is based on the experience from Dr. Alan Stern, principal investigator of the New Horizons mission and the Chief Scientist at Moon Express \cite{stern2018chasing}.
....
\end{multicols}
\begin{table}[H]

\end{table}

\begin{multicols}{2}
... more text ...
