my guess is that the following should work ok (this current code is 
quite old and dates from previous century)

\unprotect

\bgroup

\catcode`\|=\@@active
\catcode`\"=\@@active

\gdef\pushouterbarandquote
  {\ifForgetTableBarAndQuote
     \ifnum\catcode`\|=\@@active
        \let\outertablebar|%
     \else
        \let\outertablebar\relax
     \fi
     \ifnum\catcode`\"=\@@active
       \let\outertablequote"%
     \else
       \let\outertablequote\relax
     \fi
   \fi}

\gdef\popouterbarandquote
  {\ifForgetTableBarAndQuote
     \ifx\outertablebar  \relax\else\let|\outertablebar  \fi
     \ifx\outertablequote\relax\else\let"\outertablequote\fi

     \redefinetablebarandquote
