Changes:
  v.1.0 
  20000927 18:00:00 

  v.1.01
  20000930 . added 'background' property to have table image background (like clear pixels)
           . removed all default row or cell bgcoloring
           . made it so no "bgcolor=" will be printed at all if the 'tablecolor', 'rowcolor', 
             or 'tdcolor' prop is unset  
  v.1.02
  20001008 . added 'valign' property so u can line things up vertically in td cells across a row
