如何制作双列命名法

Question

我想要两列命名法。到目前为止，我有以下代码，我正在处理它。有什么想法我应该如何将它们分成两列吗？我还想删除命名法下方的打印日期。

\documentclass{article}
\usepackage[utf8]{inputenc}

\usepackage{amssymb}

\usepackage{nomencl}
\makenomenclature

%% This will add the subgroups
%----------------------------------------------
\usepackage{etoolbox}
\renewcommand\nomgroup[1]{%
  \item[\bfseries
  \ifstrequal{#1}{A}{}{%
  \ifstrequal{#1}{B}{Number Sets}{%
  \ifstrequal{#1}{C}{Other Symbols}{}}}%
]}
%----------------------------------------------

%% This will add the units
%----------------------------------------------
\newcommand{\nomunit}[1]{%
\renewcommand{\nomentryend}{\hspace*{\fill}#1}}
%----------------------------------------------

\title{Nomenclatures}


\begin{document}
\maketitle

\mbox{}

\nomenclature[A, 01]{$\dot\rho$}{D}
\nomenclature[A, 02]{$\bf \nabla$}{N}
\nomenclature[A, 03]{$\mathcal{R}$}{R}
\nomenclature[A, 04]{$\sigma$}{DS}
\printnomenclature

\end{document}

Answer 1

您可以使用两个钩子\nompreamble和\nompostamble：

\documentclass{article}
\usepackage[utf8]{inputenc}

\usepackage{amssymb}
\usepackage{multicol}

\usepackage{nomencl}
\makenomenclature

%% This will add the subgroups
%----------------------------------------------
\usepackage{etoolbox}
\renewcommand\nomgroup[1]{%
  \item[\bfseries
  \ifstrequal{#1}{A}{}{%
  \ifstrequal{#1}{B}{Number Sets}{%
  \ifstrequal{#1}{C}{Other Symbols}{}}}%
]}
%----------------------------------------------

%% This will add the units
%----------------------------------------------
\newcommand{\nomunit}[1]{%
\renewcommand{\nomentryend}{\hspace*{\fill}#1}}
%----------------------------------------------
\renewcommand{\nompreamble}{\begin{multicols}{2}}
\renewcommand{\nompostamble}{\end{multicols}}

\title{Nomenclatures}


\begin{document}
\maketitle

\mbox{}

\nomenclature[A, 01]{$\dot\rho$}{D}
\nomenclature[A, 02]{$\bf \nabla$}{N}
\nomenclature[A, 03]{$\mathcal{R}$}{R}
\nomenclature[A, 04]{$\sigma$}{DS}
\printnomenclature
\end{document}

Answer 2

只需添加\usepackage{multicol}到您的序言中然后：

\begin{multicols}{2}
\printnomenclature
\end{multicols}

我不明白日期的问题。
