Latex Beamer 错误“出了点问题——可能缺少\item。”

Question

我正在研究背面的 Latex 演示文稿。我找到了一个看起来不错的模板并开始使用 ist。发生此错误时，我正在使用列和调整大小框“出了点问题——可能缺少 \item。

当我将列与表结合使用时，我确实遇到了类似的错误。

我可以重现错误的最小代码是：

\documentclass{beamer}

\usepackage{CNU}

\begin{document}

\begin{frame}{Framename}
\resizebox{0.8\textwidth}{!}{%
\begin{table}
\begin{tabular}{lccc}
a & 1 & 2 & 3 \\
b & 4 & 5 & 6                   
\end{tabular}
\end{table}
} % close resizebox
\end{frame}

\end{document}

样式文件CNU.sty是

我找不到错误。有人可以帮助我吗？

我尝试编辑样式文件并查看了 stackoverflow 上的其他一些问题，但自己找不到解决方案。
