我想要一个多行方程（最好是相对于相应的列居中，因为我已经使用 [ 和 ] 或 $$ $$ 的单行方程没有居中）作为 \newglossaryentry 描述的一部分。
所以基本上我想要的是，在词汇表的列中，单行和多行方程式居中。
谢谢！
PS我想我可以从中得到一些东西：在此处输入链接描述 但我不能……

It is said that $f$ is holomorphically extended over $U$ if such a $g$ exists. A simple example is the function $$f(z) = \frac{\sin(z)}{z}$$ at $z=0$ (even this: \[f(z) = \frac{\sin(z)}{z}\] doesn't center.). The singularity, due to the indeterminate form, can be removed by defining $f(0)=1$, which is the limit of $f$ as $z$ approaches zero.}

答案1
将内容包装在minipage环境中可以使显示的数学运算位于longtable环境中的中心。但每次都这样做会很繁琐、不灵活且容易出错。
更好的选择是使用包\newcolumntype的命令array为表格环境设置新的列类型，然后我们可以使用它来定义新的词汇表样式my3col。此样式将基于long3col但更改了描述的列类型。
我glossaries之前已经加载了，因此\glsdescwidth在定义新列类型时可以使用。这反过来在设置将使用它的新词汇表样式之前定义。最后，新样式被激活。
