我有以下 MWE
\documentclass{article}
\usepackage{lipsum}
\usepackage{color}
\usepackage{multicol}
%-> Defining the INFORMATION environment:
\newenvironment{info}[1]
{\setlength{\parindent}{0cm}
\color{black!75}
\bigskip\par
\textbf{#1}
\small
}{\bigskip\par}
%... info environment is for info that aids solving the problems
\begin{document}
\section{Introduction}
\lipsum[1]
\section{Theory}
\lipsum[11]
\begin{info}{A square}
\begin{multicols}{2}
Observe below that I can draw a square using the \textit{tikz} package.
\begin{center}
\rule{2cm}{2cm}
\end{center}
However, I can't show this inside a \textit{picture} environment. Believe me, there should be another square below.
\begin{figure}
\centering
% \begin{tikzpicture}
% \draw
% (0, 0) circle(2)
% ;
% \end{tikzpicture}
\rule{2cm}{2cm}
\caption{There should be a cricle here.}
\label{F circle}
\end{figure}
\end{multicols}
\end{info}
\section{Conclusions}
Can't draw inside a \textit{multicol} environment, and I just don't know why.
\end{document}
为什么在这种情况下figure
内部不起作用?multicols
答案1
我将提出一种经过一整天思考后对我有用的方法。如果有任何编程级别的错误,请在评论中告诉我。
通过定义一个名为“two-column-figure”的新环境,IE,tcfigure
作为
%-> Defining the TWO-COLUMN-FIGURE environment:
\newenvironment{tcfigure}{%
\begin{center}
\begin{tabular}{ c }
}{%
\end{tabular}
\end{center}
}
%-> Defining the TWO-COLUMN-FIGURE CAPTION command:
\newcommand{\tcfcaption}[1]{%
\\
\begin{tabular}{ p{0.33\textwidth} }
\footnotesize
Figure \refstepcounter{figure}\thefigure: #1
\end{tabular}
}
现在,我可以将图形插入到我想要的位置,就像它是一个浮点数一样。完整代码如下:
\documentclass{article}
\usepackage{lipsum}
\usepackage{xcolor}
\usepackage{multicol}
%-> Defining the INFORMATION environment:
\newenvironment{info}[1]

\lipsum[1]
\section{Theory}
\lipsum[11]
\begin{info}{A square}
\begin{multicols}{2}
Observe below that I can draw a square using the \textit{bar} command, as shown below.
\begin{center}
\rule{2cm}{2cm}
\end{center}
However, I can't show this inside a \textit{picture} environment. Believe me, there should be another square below.
\begin{tcfigure}
\rule{2cm}{2cm}
\tcfcaption{%
There should be a square here. And in fact, now there is!
\label{F square}}
\end{tcfigure}
\end{multicols}
\end{info}
\section{Conclusions}
Can't draw inside a \textit{multicol} environment, and I just don't know why. But it is possible to create a new enviroment that mimics the \textit{figure} one. See it in figure~\ref{F square}.
