从 \paracol 段落全局删除缩进

Question

我使用 \paracol 来对齐跨页面的列。但是，在右侧，每个段落开始之前总会有一些缩进。请帮我避免这种情况？以下是我的代码：

Answer 1

这是一个解决方案。myparacol定义并使用一个新环境，并将其内部parindent设置为 0。

\newenvironment{myparacol}[2][]{%
\begin{paracol}{#2}[#1]\setlength{\parindent}{0pt}}{%
\end{paracol}}

要使用的\begin{myparacol}{2}...\end{myparacol}

Answer 2

或者通过使用etoolbox包：

\documentclass[11pt]{article}
    \usepackage{paracol}
    \usepackage{mdframed}
    \usepackage{lipsum}
    \usepackage{tikz}    
\def\labelaxes{Remember to include your label}    
    \usepackage[top=1.5cm, bottom=1.3cm, left=1cm, right=1.5cm]{geometry}

    \usepackage{etoolbox}% <--- added
\AtBeginEnvironment{paracol}{\setlength{\parindent}{0pt}}<--- added

\begin{document}
\columnratio{.3}
    \begin{paracol}{2}
.... 
    \end{paracol}
\end{document}
