Nomencl 包 - 将选项 nomentbl 与自定义子组组合失败

Question

我正在尝试使用该nomencl包（CTAN链接) 并希望以表格形式格式化命名法条目，如文档中所述（选项nomentbl）。

这很好，除非我还尝试按照文档中所述自定义子组（通过\renewcommand{\nomgroup}...）。附加的 MWE 在输出中返回以下错误

./mwe.nls:7: Missing number, treated as zero.

并且 PDF 中的标题都乱了（见下文）。

有人能解释一下吗？我遗漏了什么明显的内容吗？任何建议都将不胜感激！

Answer 1

\nomgroup选项并没有得到很好的支持nomentbl。当然不能使用\ifthenelse它来支持它，因为我们需要发出\multicolumn命令。

一种解决方法是使用\pdf@strcmp可扩展的字符串比较。

\documentclass{scrartcl}
\usepackage{amsmath}
\usepackage[per-mode=fraction]{siunitx}
\usepackage[nomentbl]{nomencl}
\usepackage{pdftexcmds}

\makenomenclature

\makeatletter
\renewcommand{\nomgroup}[1]{%
  \ifnum\pdf@strcmp{#1}{C}=\z@
    \multicolumn{6}{l}{\textbf{Constants}}\\%
  \else
    \ifnum\pdf@strcmp{#1}{S}=\z@
      \\\\\multicolumn{6}{l}{\textbf{Sets}}%
    \else
      \ifnum\pdf@strcmp{#1}{V}=\z@
        \\\\\multicolumn{6}{l}{\textbf{Variables}}%
      \fi
    \fi
  \fi
}
\makeatother

\printnomenclature
