我试图消除列表环境末尾的垂直空间（enumerate、itemize和），但仅当列表环境位于包中环境的describe末尾时才这样做。这种特殊情况会导致左侧栏出现尴尬的悬垂（下面的工作示例）。到目前为止，我考虑了三个选项：leftbarframed
- 我知道我可以调整
\topsep、\itemsep和\partopsep，但这不会以环境的结束为条件leftbar，也不会影响整个文档。 - 我可以重新定义列表环境以在末尾包含一些负空间。但是，这并不取决于位于环境末尾
leftbar。 - 最后，我可以根据具体情况手动实施上述两种解决方案。这似乎不太优雅，而且在较长的文档中需要做大量工作。
如果有人有解决方案，我们将不胜感激！
\documentclass{article}
\usepackage{framed}
\begin{document}
\begin{leftbar}
\begin{enumerate}
\item Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old.
\item Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old.
\end{enumerate}
\end{leftbar}
\end{document}
答案1
您可以将leftbar环境重新定义为-like 环境\unskip插入的最后一个跳过itemize。
在你的序言中添加以下几行：
\let\oldendleftbar\endleftbar
\renewcommand{\endleftbar}{\unskip\oldendleftbar}
梅威瑟：
\documentclass{article}
\usepackage{framed,lipsum}
\let\oldendleftbar\endleftbar
\renewcommand{\endleftbar}{\unskip\oldendleftbar}
\begin{document}
\begin{leftbar}
\begin{itemize}
\item Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old.
\item Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old.
\end{itemize}
\begin{enumerate}
\item Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old.
\item Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old.
\end{enumerate}
\end{leftbar}
