在另一个问题我问如何使用选项通过idxlayout包获取自定义分隔符singlepar：我想问是否可以使用该选项保留相同的分隔符abshang，仅打印单个段落中格式化的每个条目的最后一级。
例如：
\index{Author!Work1!1,15}
\index{Author!Work1!9,32}
\index{Author!Work2!2,24}
\index{Author!Work2!5,11}
\index{Author2!2,45}
\index{Author2!4,34}
\index{Author2!6,12}
\index{Author2!9,4}
应该给出这个：
以下是 MWE：

谢谢你！
编辑：通过删除此行，\renewcommand{\subitem}{\iffirstsubitem\unskip\firstsubitemfalse, \else --- \fi\firstsubsubitemtrue}%我获得了具有两个子级的索引的所需输出，但具有一个子级的索引垂直堆叠（参见图片）。

文件.ind将更加结构化，并根据结构分为以下几种情况：无子项、一级子项、两级子项。
