As Allan suggested, I think that you need to have a rule in the LaTeX grammar that will match the column specification part of the tabular environment. Instead of writing a completely new rule, I tried changing the relevant existing rule, copied below. The only difference is in the begin match. I also tried adding your rule for scoping anything between pipes as verbatim, and this change to the tabular rules seems to do what you want - anything in the column spec is not scoped as verbatim. Hope that helps!
