To answer your explicit question, you need to specify either "c" or "C"
for a column envargs setting, as in "c[<+->]" or "C[<+->]", the
difference being that with lower case c, the argument applies to the
column and with upper case C, it applies to the columns environment.
You need one of these to get the export to work.

Having said this, I have no idea how to get beam to do automatic
column overlays, as you seem to want.  I have always had to use <1->
etc.  So I would have envargs for the first column set to "c<1->" (note,
no square brackets) and "c<2->" for the second.
