+== Format
 
+This gem includes a simplified way to change the format of the cells. Also this gem provides a simplified way for changing the format of the headers.
+
+To change the format of the cells and headers the code should be like this:
+
+      User.all.to_xls :cell_format => {:color => :blue}, :header_format => {:weight => :bold, :color => :red}
+
+To have a full list of the format admited for the cells and headers you may have a look {on the source code of spreadsheet gem}[http://scm.ywesee.com/?p=spreadsheet/.git;a=blob;f=lib/spreadsheet/format.rb;h=ceef6bb6618238d1ff5cc0462826e2c127c272f1;hb=HEAD]. This gem runs under to_xls, so the format supported by this gem are the ones of spreadsheet.

 * Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
