我使用newenvironment来构造我的符号列表和缩写列表。在一些文档中，它们只有一个。因此，我尝试计算此环境的使用情况，以更正我的表列表中的偏移量，否则它会多计算一两个表，并从两个或三个开始。
我尝试过这样的：
\newcounter{tableCounter}
\renewenvironment{theglossary}{\begin{longtable}[l]{@{}p{\dimexpr 2cm-\tabcolsep}p{0.8\hsize}}}{\stepcounter{tableCounter}\end{longtable}}}
\addtocounter{table}{-\value{tableCounter}}

此 MWE 呈现：
如您所见，我的表格列表从数字 3 开始。
