One Line Column Markup

[Pato Press]

Hi, I'm sure what i'm trying is quite simple but I can't find the solution.

Is there a way of printing a column in the space of one standar line?

I'm trying something like these:

\version "2.12.2"
\markup{
    4
     \column { \super a . }
}


These gives me something like these:

  a
4
   .

Not what I'm looking for. What I need is to put the "a" character over
the "." character and both in the same line hight of the "4"
character.

I hope its clear. Thanks to anybody.
