我正在尝试为论文中使用的所有符号生成命名法。一些具有相同索引的变量应该分组，因为它们属于同一组。但是，当我尝试对它们进行分组时，命名法的布局变得一团糟。参见下面的 MWE：
\documentclass{report}
\usepackage{nomencl}
% create the lsymb command
\newcommand{\lsymb}[2]{#1\nomenclature[b ]{#1}{\MakeUppercase#2}}
% make the nomenclature
\makenomenclature
\makeindex
\begin{document}
I would like to have the variables \lsymb{$a_f$, $b_f$, $c_f$ and $d_f$}{The variables I am trying to group} group on two lines in the nomenclature.
However, when I add more variables such as \lsymb{$a_b$}{another variable} and \lsymb{$c_f$}{yet another variable}, the lay-out gets quite messy.
I could try grouping the variables, like I did with \lsymb{$d_a$, $e_a$,}{a group of variables}\lsymb{$g_a$, and $h_a$}{{}}. But that grouping order will be broken if a variable \lsymb{$f$}{some annoying variable} were to come along.
\printnomenclature
\end{document}
输出如下：
因此基本上发生的情况是：
- 将变量归入一个组会扭曲布局
- 将变量拆分到多行上会因自动字母排序而变得混乱（我希望保留）。
我正在寻找的解决方案：
- 加宽包含变量的列，以便所有描述都对齐
- 以某种方式将分组变量变成多行对象，这样其他变量就不会弄乱排序。
答案1
调用时添加可选参数，即长度，\printnomenclature例如
\printnomenclature[3cm]
