我需要将 CAS 生成的一些大型方程式放入表格中。 resizegather看起来它可以完成这项工作。但它会在每行的方程式上方和下方产生大量额外空间。
使用时会发生这种情况\begin{gather*} ... \end{gather*}。它确实在水平方向上缩小了方程式，以便适合，但我正在寻找一种方法来删除上下空格。
当使用时\begin{gathered} ... \end{gathered}，上面和下面的空间消失了，但等式不再缩小！
这是 MWE

尝试下面的答案，我没有看到方程缩小。这是新的 MWE。

太渴望评论了。为了模拟您的要求可以产生的结果，请参见以下示例：
\documentclass[12pt,parskip=full]{scrbook}
\usepackage{array}
\usepackage{resizegather}
\begin{document}
{
\addtolength\abovedisplayskip{-30pt}
\addtolength\belowdisplayskip{-25pt}
\begin{tabular}[c]{|m{0.55in}|l|}\hline
Solution & Verification \\ \hline
%\vspace*{-5ex}
\begin{gather*}
y=\sin x \tan x\int \cos x + 3 x\sin x\tan x
\end{gather*}
%\vspace*{-4ex}
& OK \\ \hline
\end{tabular}
}
\end{document}
预期结果很丑陋且无用：

请注意，该gathered环境位于一些其他数学环境内，因此对于包来说不可见resizegather，因此它无法影响“聚集”。
我建议你采用另一种方法，（在我看来）这种方法效果更好。通过使用包\medmath中的宏nccmath和使用makecell包，你可以获得以下结果：
\documentclass[12pt,parskip=full]{scrbook}
\usepackage{nccmath}
\usepackage{makecell}
\setcellgapes{5pt}
\usepackage{resizegather}
\begin{document}
No wasted extra space here in the vertical direction,
but the math do not scale as expected
{\makegapedcells
\begin{tabular}{|l|l|}
\hline
Solution & Verification \\
\hline
$\medmath{
\begin{gathered}
y = \sin x\tan x \int\cos x +3 x\sin x\tan x
\end{gathered} }
$ & OK \\
\hline
\end{tabular}
}
Here the math scales as expected to fit, but lots of extra
wasted extra space in the vertical direction
\begin{tabular}[c]{|m{2in}|l|}\hline
Solution & Verification \\ \hline
\begin{gather*}
y=\sin x \tan x\int \cos x + 3 x\sin x\tan x\end{gather*}
& OK \\ \hline
\end{tabular}
If you are limited with horisontal space for equation you may consider to split equation into two lines and not reduce font size to much:
{\makegapedcells
\begin{tabular}{|l|l|}
\hline
Solution & Verification \\
\hline
$
\begin{multlined}
y = \sin x\tan x \\[-3ex]
\int\cos x dx + 3 x\sin x\tan x
\end{multlined}
$ & OK \\
\hline
\end{tabular}
or with use of \verb+\medmath+:
{\makegapedcells
\begin{tabular}{|l|l|}
\hline
Solution & Verification \\
\hline
$\medmath{
\begin{multlined}
y = \sin x\tan x \\
\int\cos x dx + 3 x\sin x\tan x
\end{multlined} }
$ & OK \\
\hline
\end{tabular}
\end{document}
