我从 Christian Hupfer 那里找到了这个用于词汇表设置的漂亮代码。我想更改描述和单位的顺序（符号、单位、描述），但我找不到在交换时如何调整列宽的方法。我该怎么做才能使描述宽度比符号和单位宽度更长？

我使用了下面的样式并且接近我需要的。
\newglossarystyle{3colger}{%
\setglossarystyle{longragged3col}% base this style on the list style
\renewenvironment{theglossary}{% Change the table type --> 3 columns
\begin{longtable}{l l p{\glsdescwidth}}}%
{\end{longtable}}%
%
\renewcommand*{\glossaryheader}{% Change the table header
\bfseries Zeichen & \bfseries Einheit & \bfseries Beschreibung \\
% \hline
\vspace{0.05cm}
\endhead}
\renewcommand*{\glossentry}[2]{% Change the displayed items
\glstarget{##1}{\glossentryname{##1}} %
& \glsunit{##1}
& \glossentrydesc{##1} \tabularnewline
}
}
剩下的问题是，如果第三列的条目太长，它就不会中断。有没有办法彻底中断？
