在列表/两列中对齐文本

tag-icon • tag-icon horizontal-alignment lists text
在列表/两列中对齐文本

我列出了带有描述的事物，但有些描述不太适合这一行，使得列表看起来不太美观。我目前得到的只是一个 itemize 环境，它看起来有点像这样

item in list: item description
another item in list:
description of the item that is too long for
the line and it goes down here
third item in list: a description that fits

我想要做的是：

item in list:         item description
another item in list: description of the item that is too long for
                      the line and it goes down here
third item in list:   a description that fits

或者

        item in list: item description
another item in list: description of the item that is too long for
                      the line and it goes down here
  third item in list: a description that fits

我尝试了对齐环境，但没有起到作用。

我一直在尝试寻找解决方案，但我真的不知道该用谷歌搜索什么。

答案1

您可以使用longtable环境。在下面的示例中，我选择p让第二列允许自动换行。设置列宽p以适合您的页面布局（我们目前对此一无所知）。

\documentclass{article}
\usepackage{longtable}
\begin{document}
\begin{longtable}{ l p{3in} } % choose suitable width for "p" column
item in list: & item description \\
another item in list: & description of the item that is too long for the line and it goes down here\\
third item in list: & a description that fits\\
\end{longtable}
\end{document}

这里还有更多选项，使用tabularx或列表（通过enumitem) 以充分利用文本块宽度。

在此处输入图片描述

\documentclass{article}
\usepackage{tabularx,array}
\usepackage{enumitem}
\begin{document}

\noindent
\begin{tabularx}{\textwidth}{@{}l<{:}@{\ }X@{}}
  item in list         & item description \\
  another item in list & description of the item that is too long for
                         the line and it goes down here \\
  third item in list   & a description that fits
\end{tabularx}

\bigskip

\noindent
\begin{tabularx}{\textwidth}{@{}r<{:}@{\ }X@{}}
          item in list & item description \\
  another item in list & description of the item that is too long for
                         the line and it goes down here \\
    third item in list & a description that fits
\end{tabularx}

\bigskip

\newsavebox{\descbox}
\savebox{\descbox}{\bfseries another item in list:}
\SetLabelAlign{Left}{\makebox[\wd\descbox][l]{#1}}
\begin{description}[leftmargin=\dimexpr\wd\descbox+\labelsep,align=Left]
  \item[in list:]              item description
  \item[another item in list:] description of the item that is too long for
                               the line and it goes down here
  \item[third item in list:]   a description that fits
\end{description}

\bigskip

\SetLabelAlign{Right}{\makebox[\wd\descbox][r]{#1}}
\begin{description}[leftmargin=\dimexpr\wd\descbox+\labelsep,align=Right]
  \item             [in list:] item description
  \item[another item in list:] description of the item that is too long for
                               the line and it goes down here
  \item  [third item in list:] a description that fits
\end{description}

\end{document}

类似方法tabular（前两种）不会跨越页面边界，而类似列表的方法（后两种）则会。

所有格式都可以根据您的需要进行定制。
