Thank you so much, Murray. In ruby works fine also.

   renderer = Gtk::CellRendererText.new
   column = Gtk::TreeViewColumn.new("Prize", renderer,'text' => 
PRIZE_COLUMN)
   column.set_cell_data_func(renderer) {|column, cell, model, iter|
   cell.text=sprintf("%.2f",iter[PRIZE_COLUMN])
   }


Ruby-gnome Rocks!!!!!!!!!!!!!!!!!
