Rails - Jul 2009 - How to display data in grid format?

Hi all,

I have a problem that i want to print data in grid (table format)

following is my partial file named "_coupon.haml.html"
-coupon_template.each do |template_data|
  -coupon.initializeFromTemplate(template_data)
  #div{:style=>"border: solid; border-color: gray; width: 310px;"}
    =haml_engine
Haml::Engine.new(CouponTemplate.find(coupon.template_id).data).render(Object.new,
:coupon => coupon)
  %input{:type=>''radio'',
:name=>''coupon_template_id'', :value=>
template_data.id}
  %br
  %br
%br
%br
%hr
%table{:width => "100%"}
  %tr
    %td{:align => "right"}
      =link_to "Cancel", polymorphic_path(coupon.business)
      = submit_tag ''Next Step''


Currently i am printing coupons one after one.
I want it like following

---------------------------------------------------------
 coupon 1          |     coupon 2     |    coupon 3      |
                   |                  |                  |
-------------------|------------------|------------------|
 coupon 4          |     coupon 5     |    coupon 6      |
                   |                  |                  |
-------------------|------------------|------------------|

I tried but there is no for loop such that

for i=0, i<coupons.length, i+=3

Look at the AR docs for @collection.in_groups_of if you want to process 
the coupons in groups of 3.

@collection.in_groups_of is very helpful
