itemize 内的制表位和换行

tag-icon • tag-icon lists line-breaking itemize tabbing
itemize 内的制表位和换行

我想要实现的目标：

some list:
- some text
- Def.:  Some long text which should both automatically wrap to a new line
         and be tabbed as displayed here.
- some sublist
  * with the new counter
  * Def.:  same as above, but note that the counter matches the list level

这答案最接近，但如果使用里面在其他一些列表中，计数器（我的意思是项目符号）不匹配，前后间距较大。此外，我不需要制表符来跨多个项目符号工作（与原始问题相反），这可能会简化事情。

我希望我的问题已经清楚了。如果不清楚，请告诉我！并不是因为我懒得使用 MWE，而是因为我无法接近我想要的（除了简单的itemize）。谢谢！

（只是为了澄清：我不想自己指定任何项目符号样式，它们只是随着列表级别的增加而改变。）

答案1

我不确定您是否已指定所有要求，但这里有三种方法可以解决这个问题。第一种方法基于环境tabular，不允许在缩进的文本中添加新段落。第二种使用minipage缩进的文本现在可以分成段落。第三种是@egreg 的建议，使用 enumitem 包和描述列表；这将跨页面划分，但不会推广到其他制表位（如果您需要的话）。

首先是前两个解决方案：

示例输出

\documentclass{article}

\newcommand*{\tabulardef}[3]{\begin{tabular}[t]{@{}lp{\dimexpr\linewidth-#1}@{}}
    #2&#3
  \end{tabular}}

\newlength{\standardparindent}
\setlength{\standardparindent}{\parindent}
\newenvironment{minipdef}[2]{\makebox[#1]{#2\ \hfill}%
  \begin{minipage}[t]{\dimexpr\linewidth-#1}%
  \setlength{\parindent}{\standardparindent}\noindent\ignorespaces}%
{\end{minipage}}

\begin{document}

\subsection*{Tabular example}

Some list:
\begin{itemize}
\item Some text which is long and wraps on to the next line as usual
  as this is demonstrating
\item \tabulardef{2cm}{Definition}{Some long text which should both
  automatically wrap to a new line and be tabbed as displayed here.}
\item Some sublist
  \begin{itemize}
  \item with the new counter and some text which is long and wraps on
    to the next line as usual as this is demonstrating
  \item \tabulardef{2cm}{Definition}{Some long text which should both
    automatically wrap to a new line and be tabbed as displayed here.}
  \end{itemize}
\end{itemize}

\subsection*{Minipage example}

Some list:
\begin{itemize}
\item Some text which is long and wraps on to the next line as usual
  as this is demonstrating
\item \begin{minipdef}{2cm}{Definition}
    Some long text which should both automatically wrap to
    a new line and be tabbed as displayed here.

    This also contains new paragraphs with long text for demonstration
    purposes.
  \end{minipdef}
\item Some sublist
  \begin{itemize}
  \item with the new counter and some text which is long and wraps on
    to the next line as usual as this is demonstrating.
\item \begin{minipdef}{2cm}{Definition}
    Some long text which should both automatically wrap to
    a new line and be tabbed as displayed here.

    This also contains new paragraphs with long text for demonstration
    purposes.
  \end{minipdef}
  \end{itemize}
\end{itemize}

\end{document}

在表格中，第一列左对齐，包含标题，后续文本位于一p列中。第一列之前和最后一列之后的额外间距已根据@{}规范删除。

迷你页面案例，首先在框中设置标题，然后开始迷你页面。我已经设置好了，以便后续段落具有正文的标准段落缩进；如果没有一些缩进，很难看到它们从哪里开始。

现在第三个解决方案是enumitem：

示例 enumitem 输出

\documentclass{article}

\usepackage{enumitem}

\newlist{deflist}{description}{2}
\setlist[deflist]{labelwidth=2cm,leftmargin=!,font=\normalfont}

\begin{document}
Some list:
\begin{itemize}
\item Some text which is long and wraps on to the next line as usual
  as this is demonstrating
\item
  \begin{deflist}
  \item[Definition]Some long text which should both automatically wrap
    to a new line and be tabbed as displayed here.
  \end{deflist}
\item Some sublist
  \begin{itemize}
  \item with the new counter and some text which is long and wraps on
    to the next line as usual as this is demonstrating
  \item
    \begin{deflist}
    \item[Definition]Some long text which should both automatically
      wrap to a new line and be tabbed as displayed here.

      This also contains new paragraphs with long text for
      demonstration purposes.
    \end{deflist}
  \end{itemize}
\end{itemize}

\end{document}
