The problem is not with mm macros and not with vertical bars.

     .EQ
     delim ##
     .EN
     .TS
     l l.
     xxxxxxxxxx\txxxxxxxxxx
     #dW over dt#\txxxxxxxxxx
     .TE

The first problem is that tbl must be invoked first;
the reason it produced real junk is that tbl uses number registers
whose names contain the character "#" and so eqn thinks it begins an equation.

Use "$" or "@" for the equation delimiter and all is well!
