Looks fine:\blank
\midaligned{%
\xttable{Statement X}{Statement Y}{$\Rightarrow$}%
{unknown}{unknown}{invalid (false)}{valid (true)}
}


 This doesn't work:\blank
\midaligned{%
\xttable{Some sort of longer statement}{Another sort of longer statement}%
{$\Rightarrow$}%
{unknown}{unknown}{invalid (false)}{valid (true)}
}

% This doesn't work either:\blank
% \midaligned{%
% \xttable{\framed[width=2cm,frame=off]{Some sort of longer
% statement\par}}{\framed[width=2cm,frame=off]{Another sort of longer
