It seems that I cannot reference tables when they are placed inside onlyenv, but . This applies to both of cref and the traditional ref

Here is the MWE. When you try to run it, you must do so twice to get the real result.

usecolortheme{seahorse}

useoutertheme{miniframes}

setbeamertemplate{caption}[numbered]

newcommand{framePageWide}{

    defGm@lmargin{5mm}%

    defGm@rmargin{5mm}%

    columnwidthtextwidth

    setlength{linewidth}{textwidth}

    hoffset=dimexpr-beamer@leftsidebar+Gm@lmargin-0mmrelax

}

makeatother

newcommand{framePageWideEnumI}{setlength{leftmargini}{10mm}}





    usepackage{adjustbox}

    usepackage{booktabs}

    usepackage{amssymb, amsfonts}



    usepackage{cleveref}

    crefformat{table}{Table #1}





begin{document}

    begin{table}



        begin{adjustbox}{minipage={0.5textwidth}, valign=t}



            caption{Time, in seconds, needed to calculate a single ${Z}_{bus}$ Element}

            label{table:results2}



            begin{tabularx}{linewidth}{c C C}



                toprule

                addlinespace



                200-bus & $4.3times10^{-6}$ & $0.092$

                \

                Xhline{0.25mm}



                2383-bus & $3.8times10^{-6}$ & $166.2$

                \

                Xhline{0.25mm}



                3120-bus & $3.2times10^{-6}$ & $398.8$

                bottomrule

        end{adjustbox}

        hfill

        begin{adjustbox}{minipage={0.43textwidth}, valign=t}



            From cref{table:results2} we see that



            begin{itemize}

                item Our method is fast

                item By contrast, Brown's becomes very slow when the system is large

            end{itemize}



        end{adjustbox}



    end{table}



end{onlyenv}





end{frame}



}
