减少描述列表中标签和项目之间的空间

Question

我有我正在使用的描述列表，例如

\begin{description}
    \item[Video recordings] arguably produced the richest part of the data set.
    \item[Questionnaires] were no second, mind you!
\end{description}

不幸的是，这会导致标签和项目之间的空格大于同一行上单词之间的常规空格：

我可以做些什么来使“视频录像”和“可以说”之间的空间等于“可以说”和“制作”之间的空间？

Answer 1

\documentclass[12pt]{article}
\usepackage{enumitem}
\begin{document}

\begin{description}[labelsep=\fontdimen2\font]
    \item[Video recordings] arguably produced the richest part of the data set.
    \item[Questionnaires] were no second, mind you!
\end{description}

\end{document}

要控制标签和项目之间的间距，您可以更改列表labelsep的参数description（可从enumitem包中获得）。要获得常规单词间距，您需要\fontdimen2（正常的单词间距）labelsep。这是通过传递以下内容来完成的：

[labelsep=\fontdimen2\font]

作为description环境的一种选择。

Answer 2

正在加载enumitem，你可以玩labelsep：

\documentclass{article}
\usepackage{enumitem}

\begin{document}

\begin{description}[labelsep=0pt]
    \item[Video recordings] arguably produced the richest part of the data set.
    \item[Questionnaires] were no second, mind you!
\end{description}


\begin{description}[labelsep=2cm]
    \item[Video recordings] arguably produced the richest part of the data set.
    \item[Questionnaires] were no second, mind you!
\end{description}

\end{document} 

Answer 3

这是可能的，通过稍微扩展列表模型；在这种情况下，description这不是一个大问题假如不要在里面嵌套枚举列表description。

\documentclass{article}
\usepackage{lipsum} % for context

\makeatletter
\renewenvironment{description}
  {\list{}{%
    \labelwidth\z@
    \itemindent-\leftmargin
    \labelsep=\z@
    \let\makelabel\descriptionlabel
    \let\item\desc@item
  }}
  {\endlist}
\def\desc@item[#1]{\@item[#1]\ \ignorespaces}
\makeatother

\begin{document}
\lipsum*[2]
\begin{description}

\item[Video recordings] arguably produced the richest part of the data set.

\item[Questionnaires] were no second, mind you! Some text that should
  make the~text~wrap over a couple of lines

\end{description}
\end{document}

Answer 4

温和的替代品egreg 的回答如果你想将常规description与修改后的混合bfdesc：

\documentclass{article}
\usepackage[paper=a6paper,showframe]{geometry}% Just for this example

\newenvironment{bfdesc}
  {\begin{description}
   \let\olditem\item
   \renewcommand{\item}[1][]{%
     \olditem% Set old \item without [..]
     \hspace*{-\labelsep}% Remove \labelsep
     {\bfseries ##1}% Set new \item
     \space% Insert space (\ )
     \ignorespaces}}% Ignore any following spaces
  {\end{description}}

\begin{document}

\begin{description}
  \item[Video recordings] arguably produced the richest part of the data set.
  \item[Questionnaires] were no second, mind you!
\end{description}

\begin{bfdesc}
  \item[Video recordings] arguably produced the richest part of the data set.
  \item[Questionnaires] were no second, mind you!
\end{bfdesc}

\end{document}
