Easylist：垂直间距

Easylist：垂直间距

使用easylist，如何设置各个“级别”之间的垂直间距？（手册中的第 8 页似乎是该问题的适当部分，但我仍然感到困惑。）例如，1 级条目与另一个 1 级条目之间的垂直间距；1 级条目与 2 级条目之间的垂直间距；2 级条目与 2 级条目之间的垂直间距；2 级条目与 3 级条目之间的垂直间距；3 级条目与 3 级条目之间的垂直间距。

关于第 8 页的参考easylist手动的非常详细。也许下面的插图会有所帮助：

...             |    ...
Level n item    |    Level !=n item
Spacen*         |    Spacen
Level n item    |    Level n item
...             |    ...

例如，Space1如果前一个项目来自某一级别，则设置第一级项目之前的垂直间距以外1 级；Space1*如果前一个项目来自相同的级别。以下是示例：

\documentclass[12pt]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage[american]{babel}
\usepackage{microtype}
\usepackage{libertine}
\usepackage[at]{easylist}
\ListProperties(Hang=true,Margin=-3pc, Align=3pc, Indent=1em)
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{document}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{easylist}
\ListProperties(Space1=0.75cm, % Level not 1, Space1,  Level 1
                Space1*=0.25cm,% Level 1,     Space1*, Level 1
                Space2=1cm,    % Level not 2, Space2,  Level 2
                Space2*=0.5cm, % Level 2,     Space2*, Level 2
                Space3=0.33cm, % Level not 3, Space3,  Level 3
                Space3*=0.1cm, % Level 3,     Space3*, Level 3
                )
@ Level 1, item 1

@ Level 1, item 2

@@ Level 2, item 3

%@@ Level 3, item 4
@@ Level 2, item 4

@ Level 1, item 5

@@ Level 2, item 6

@@@ Level 3, item 7

项目间距

由于实施 easylist，特别是在以下代码中发现 easylist.sty

\expandafter\ifnum\el@PreviousItem=\el@CounterLevel
    \vskip\csname Space\the\el@CounterLevel*\endcsname
\else
    \vskip\csname Space\the\el@CounterLevel\endcsname
\fi

我们看到：如果前一个项目和当前项目处于同一级别，则Spacen*使用；否则，Spacen使用。

要定义第 3 级和第 2 级之间的垂直空间，只能通过指定 来实现Space2。要定义第 3 级和第 1 级之间的垂直空间，只能通过指定 来实现Space1。要点是：考虑垂直空间前当前项目，而不是后。
