Using defs/macros in @Cell definitions

[Milan Zamazal]

I'd like to use macros in table @Row definitions but I couldn't find out
how to do it in Lout 3.24.

What I want is something like:

  macro @specialcell { @Cell width { 1p } }
  ...
  @Row format { ... | @specialcell C | ... }

Lout complains about an unknown symbol @Cell -- I don't know what to
import to avoid this.

When I try

  macro @specialcell { width { 1p } }
  ...
  @Row format { ... | @Cell @specialcell C | ... }

it doesn't work either -- `width' is not considered being an option,
it's put into the table as a word instead.

Thanks,
