How do you get footnotes to work in xtables?  I get the superscript next to the text but the footnote does not appear at the bottom of the page.

Thanks, Clyde

MWE:

\starttext

    \startxtable

        \startxrow

            \startxcell Alpha \stopxcell

            \startxcell Beta\footnote{Footnote Here} \stopxcell

        \stopxrow

        \startxrow

            \startxcell Beta \stopxcell

            \startxcell Alpha\stopxcell

        \stopxrow

    \stopxtable

\stoptext
