actually this is a combined problem:

(1) in table there is a math switch (the following patch removes that one)

and

(2) you feed #1 to the macro while still in table mode and therefore in 
the math mode (outer box) and so the , is active etc etc, a solution for 
that is (for the unpatched table macro) to do a two step macro

\def\!ttBeginTableA[#1]{%
  \if #1u%                  % "unboxed" table
    \ifmmode
      \def\!ttEndTable{%    % user had better be in display math mode
        \relax}%            %   and have only one table at the outer level
    \else                   % user had better be in vertical mode
      \bgroup
      \def\!ttEndTable{%
        \egroup}%
    \fi
  \else
    %\hbox\bgroup $
    %\def\!ttEndTable{%
    %  \egroup %   for the \vtop, \vbox, or \vcenter, yet to come
    %  $%          for math mode
