Paragraph breakings nested in definitions

[Tamas Papp]

I'm trying to process a list of Spanish verb conjugations with lout,
generated by another program. I defined

def @Verb
        left x
        named Gerundio { }
        named Participio { }
        named PresenteOne { }
        named PresenteTwo { }
        named PresenteThree { }
        ...
{
        @LP
        @Tbl
                aformat { @Cell @B A | @Cell B | @Cell C | @Cell D | @Cell E | 
@Cell F | @Cell G }
                bformat { @Cell @ShadowBox A | @Cell @B B | @Cell @B C | @Cell 
@B D | @Cell @B E | 
                        @Cell @B F | @Cell @B G }
        {
                @Rowb
                        A { x }
                        B { yo }
                        C { tu }
                        D { el"/"ella}
                        E { nosotros }
                        F { vosotros }
                        G { ellos"/"ellas }
                @Rowa
                        A { "Presente" }
                        B { PresenteOne }
                        C { PresenteTwo }
                        D { PresenteThree }
                        ...
        }
        
}

And then, I have a header file, with SysInclude's and all other
setup. It's really short, and @Include's a file containing the actual
conjugations, in the format

beber @Verb
Gerundio { bebiendo }
Participio { bebido }
PresenteOne { bebo }
PresenteTwo { bebes }
PresenteThree { bebe }
...

ir @Verb
Gerundio ...

ser @Verb
Gerundio ...

My problem is that lout puts the tables side by side, not above each
other (and of course, scales them). I don't really understand why, but 
I think because the definition already encapsulates the verbs, so the
effect of @LP is lost. If not, what's the real reason? I don't suppose 
it's a bug, but I'm using version 3.16.

Is there any way to achieve what I want? I could make the program that 
generates the verbs output @LP, but I'm interested in other solutions.
