7 If someone desperately needs partial "structures" (such as a few
8 cells of an array inset or similar) (s)he could uses the
9 following hack as starting point to write some macros:
14 \def\makeamptab{\catcode`\&=4\relax}
15 \def\makeampletter{\catcode`\&=11\relax}
16 \def\b{\makeampletter\expandafter\makeamptab\bi}
