# Beamer option breaks align-in-tabular

I'm trying to put an align environment inside of a tabular environment. Here is a snippet:

%\documentclass[xcolor=table]{beamer}
\documentclass{beamer}

\begin{document}

\begin{tabular}{p{0.8\textwidth}}
\begin{align*}
x^{2}+2x+1 = 0
\end{align*}
\end{tabular}

\end{document}


As written, the document compiles just fine. With the commented documentclass (setting xcolor=table), I get the following error:

! Misplaced \omit. \math@cr@@@ ...@ \@ne \add@amps \maxfields@ \omit \kern -\alignsep@ \iftag@ ... l.10 \end{align*}  Why?

• Replace \begin{align*} with \begin{aligned} and \end{align*} with \end{aligned}. – Mico Jun 29 '18 at 13:38

Replacing \begin{align*} with \begin{aligned} and \end{align*} with \end{aligned} lets you compile the test file.
That said, it's not at all clear why you'd wish to employ an align* environment to begin with, since no alignment of any kind is being performed.
