IEEE 命名法，表格很长

Question

我正在为 IEEE 双栏文档准备命名法。我从以下开始：

如何在命名法中创建章节？

不幸的是，longtable在我的情况下，效果不佳。因此，我将其替换为xtabular。（我也试过，supertabular但效果不好）

产生的输出xtab提供了预期的结果，但是由于xtab包定义了许多已由 定义的命令，因此编译器返回了几条错误消息glossaries。

如何通过保留相同的输出来解决这个问题？

\documentclass[journal]{IEEEtran}

\usepackage{lipsum}  
\usepackage[acronym,nonumberlist]{glossaries}
\usepackage{xtab}

\renewcommand{\acronymname}{Nomenclature}

\newglossarystyle{mystyle}{%
  \setglossarystyle{long}%
  \renewenvironment{theglossary}%
     {\begin{xtabular}[l]{@{}p{0.1\hsize}p{0.8\hsize}}}%
     {\end{xtabular}}%
  \renewcommand*{\glsgroupheading}[1]{%
     \multicolumn{2}{@{}l}{\itshape\glsgetgrouptitle{##1}}\\[5pt]}%
}
