Enumeration in the `parcolumns` environment

Question

I am encountering a problem in the parcolumns environment.

\documentclass{article}
\usepackage[top=1in, bottom=1in, left=1in, right=1in]{geometry}
\usepackage{amsmath} 
\usepackage{amsfonts}
\usepackage{parcolumns}
\usepackage{enumitem}

\begin{document}


\begin{parcolumns}[rulebetween=false]{2}
\colchunk[1]{\textbf{Logical properties of \emph{before}}
\begin{enumerate}[resume]
\item $(p \vee q)$B$r \longleftrightarrow (p\text{B}r \vee q\text{B}r)$
\item $p$B$(q  \vee r) \longleftrightarrow (p\text{B}q \wedge p\text{B}r)$ 
\item $p$B$q   \longrightarrow p$
\end{enumerate}}
\colchunk[2]{\textbf{Logical properties of \emph{before}}
\begin{enumerate}[resume]
\item $(p \vee q)$A$r \longleftrightarrow (p\text{A}r \vee q\text{A}r)$
\item $p$A$(q  \vee r) \longleftrightarrow (p\text{A}q \vee p\text{A}r)$
\item $p$A$q   \longrightarrow p$
\item $p$A$q   \longrightarrow q$
\end{enumerate}}
\end{parcolumns}

\end{document}

I want the numbering to continue and not to be the same on the two lists. Any ideas on how to achieve this?

Answer 1

You need to use resume*= and define a name for the series:

Code:

\documentclass{article}
\usepackage[top=1in, bottom=1in, left=1in, right=1in]{geometry}
\usepackage{amsmath} 
\usepackage{amsfonts}
\usepackage{parcolumns}
\usepackage{enumitem}
\begin{document}
\begin{parcolumns}[rulebetween=false]{2}
\colchunk[1]{\textbf{Logical properties of \emph{before}}
\begin{enumerate}[series=X]
\item $(p \vee q)$B$r \longleftrightarrow (p\text{B}r \vee q\text{B}r)$
\item $p$B$(q  \vee r) \longleftrightarrow (p\text{B}q \wedge p\text{B}r)$ 
\item $p$B$q   \longrightarrow p$
\end{enumerate}}
\colchunk[2]{\textbf{Logical properties of \emph{before}}
\begin{enumerate}[resume*=X]
\item $(p \vee q)$A$r \longleftrightarrow (p\text{A}r \vee q\text{A}r)$
\item $p$A$(q  \vee r) \longleftrightarrow (p\text{A}q \vee p\text{A}r)$
\item $p$A$q   \longrightarrow p$
\item $p$A$q   \longrightarrow q$
\end{enumerate}}
\end{parcolumns}
