双栏纸张的页宽表

Question

我想制作一个与图片中相似的表格，但我不知道该怎么做。它必须是双列文档中的页宽表格。

我尝试过tabulary和，但我对 LaTeX 还不太熟悉。你能帮我解决这个问题吗tabularx？tabular*

我现在的代码是：

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\subsection{Computational process and algorithm}

First of all we created the conventional cells of the different phases of \ce{Bi2O3} studied. The data required to build those cells is summarized on the

\begin{table}[ht]
\centering
\caption{My caption}
\label{my-label}
\begin{tabular}{@{}lllll@{}}
\toprule
Polymorph                            & Crystal structure & Space group & Lattice Parameters                                     & Structural Parameters \\ \midrule
$\alpha$-\ce\{Bi2O3\}                & monoclinic        & P2\_1/C     & =5.849 (5.872)\par b=8.167 (8.126)\par c=7.510 (7.412) &                       \\
$\beta$-\ce\{Bi2O3\}                 & tetragonal        & P-421C      &                                                        &                       \\
$\gamma$-\ce\{Bi2O3\}                & cubic             & I23         &                                                        &                       \\
$\delta$-\ce\{Bi2O3\} (Battle model) & cubic             & Fm-3m       &                                                        &                       \\ \bottomrule

Answer 1

正如@Mico 所述你应该使用table*

\documentclass[twocolumn]{revtex4}
\usepackage{booktabs}
\usepackage{lipsum}
\begin{document}

\lipsum[1]

\begin{table*}[ht]
\centering
\caption{My caption}
\begin{tabular}{ll}
    A very long & table that must span two columns \\
    Because otherwise it will & not fit in the space provided
    by a single column\\
\end{tabular}
\end{table*}

\lipsum[2]

\end{document}
