   Define a column group  a column group corresponds to the

   the following properties tht will be shared amongst all cells in the
   columns in the group unless overidden in the specific oell definition:
   
   =over 2
   
   =item span 
   
   The number of columns in the column group.  This defaults to 1.
   
   =item halign
   
   Horizontal alignment of the cells.  This defaults to left.
   Other values are left, center, right (justify and char are 
   accepted but treated as left).
     
   =item valign
   
   Vertical alignment of the cells.  This defaults to middle.
   Other values are top middle, bottom, (baseline is accepted and
   treated as top).
   
   =back   
   
   If group borders are turned on, a rule will be rendered
   at the left and right side of the column group.
