[comp.text.tex] how to allocate a vertical space that spawns 2 columns in twocolumn documentstyle ?

oliveria@caen.engin.umich.edu (ROQUE DONIZETE DE OLIVEIRA) (03/28/91)

In latex, using the twocolumn documentstyle (or some other style that would produce
two-column output), is it possible to allocate a vertical space that spawns both columns ?
I want it to look like this:
     blah1-blah1 blah1-blah1 blah1-blah1      blah2-blah2 blah2-blah2 blah2-blah2
     blah1-blah1 blah1-blah1 blah1-blah1      blah2-blah2 blah2-blah2 blah2-blah2
     blah1-blah1 blah1-blah1 blah1-blah1      blah2-blah2 blah2-blah2 blah2-blah2
     ----------------------------------------------------------------------------

     |                                                                          |
     ----------------------------------------------------------------------------
     blah1-blah1 blah1-blah1 blah1-blah1      blah2-blah2 blah2-blah2 blah2-blah2
     blah1-blah1 blah1-blah1 blah1-blah1      blah2-blah2 blah2-blah2 blah2-blah2
     blah1-blah1 blah1-blah1 blah1-blah1      blah2-blah2 blah2-blah2 blah2-blah2
     blah1-blah1 blah1-blah1 blah1-blah1      blah2-blah2 blah2-blah2 blah2-blah2
     blah1-blah1 blah1-blah1 blah1-blah1      blah2-blah2 blah2-blah2 blah2-blah2
     blah1-blah1 blah1-blah1 blah1-blah1      blah2-blah2 blah2-blah2 blah2-blah2
     

Thanks.
