对于我的书，我使用具有不对称页面布局的回忆录文档类（旋转边距是外边距的一半）。对于索引，我使用adjmulticol在三列格式中有一个索引位置idxlayout。这几乎可以正常工作……除了所有项目都在一页上！当页面已满时，即页面不会按预期中断（参见下面的示例），并且当 adjmulticol 中有其他（非索引）文本时也是如此。
是什么原因导致了这种行为？有没有更好的方法来实现预期的结果？
编辑：
在我最初的问题中，不幸的是我删掉了三行：
\usepackage{calc}
文档类之后立即
\setlength{\marginwidth}{\marginparsep+\marginparwidth}
\setlength{\headwidth}{\textwidth+\marginwidth}
在 \usepackage{adjmulticol} 之前，这说明了为什么我实际上嵌套了一个adjmulticol和idxlayout。
我在实际情况下使用 \marginwidth 长度来计算 \headwidth 和其他项目（例如章节标题布局、扩展到外边距的新环境）。我希望我的问题更加清楚。
我需要更宽的文本宽度来在索引中放置更长的索引，以免它们不必要地分成两行。

答案1
我的idxlayout包重新定义了theindex环境，以便它使用multicols环境。你\printindex在一个adjmulticols环境中封闭（据我所知，是经过修改的multicols），这会导致嵌套( adj)multicols环境。缺少分页符似乎表明不支持嵌套这些环境。
我不确定您到底想实现什么——您定义了一个新的长度\marginwidth，但从不将其从默认值 0pt 更改。我还怀疑更改文档中间的边距（紧接在 之前\printindex）是满足您需求的正确解决方案，并且也可以使用memoir-specific 方法。但是，这里有一个有点 hack 的解决方案：我们可以修补环境theindex（由 重新定义idxlayout），以便multicols将其替换为adjmulticols（加上后者环境所需的参数）。
