each_with_index, part of the Enumerable module.

<% @ec_orders.each_with_index do |ec_order, index| %>
  <tr <%= classify(index) %>>
    <td><%=h ec_order.ship_first_name %></td>
    <td><%=h ec_order.ship_last_name %></td>
    <td><%=h ec_order.invoice_num %></td>
    <td align="center"><%= link_to 'View', {:action => 'view', :id =>
ec_order.id} %></td>
  </tr>
<% end %>
