# How to fit sidewaystable and sidewaysfigure in one page

I want to put one sidewaystable and one sidewaysfigure in one page to save page space. However, according to this link, these sideways floats always placed on a page of its own. I am wondering if there is any technique that achieves the same effect, while not necessarily adopting the "sideways" approach?

if figure and table are in the same float, they will be placed on the same page

\documentclass{article}
\usepackage{graphicx}
\usepackage{caption}
\usepackage{rotating}
\usepackage{pdflscape}

\begin{document}

\begin{sidewaystable}
\centering
\begin{tabular}{cc}
a & b \\
a & b \\
\end{tabular}
\caption{Caption}

\vspace{1cm}
\includegraphics[width=2cm]{example-image}
\captionof{figure}{image caption}
\end{sidewaystable}

\end{document}
