div_for within a table - ruby-on-rails-3

Question

I am trying to create a table that populates based on all of the records for a specific model.
Here is the index.html.erb file
<%= div_for(#departments, :class => "test") do |department| %>
<tr>
<td class="indexc1">
<%= department.name %>
</td>
<td class="indexc2">
<%= department.location %>
</td>
<td class="indexc3">
<%= department.date_completed %>
</td>
<td class="indexc4">
<ul class="action">
<li><%= link_to 'Edit Info', edit_department_path(department), :class=>"tlink3" %></li>
<li><%= link_to 'Edit Tasks', department_path(department), :class=>"tlink3" %></li>
<li><%= link_to 'Destroy', department, method: :delete, data: { confirm: 'Are you sure?' }, :class=>"tlink3" %></li>
</ul>
</td>
</tr>
<% end %>
This seems to properly create the table rows but does not put them into divs as expected.
I would like to be able to create one table row for each department and then be able to use AJAX to add or remove them.

If you want each row to be wrapped in a div, you'll need to add the div class and id to the tr tag, IE: (tr id="myid" class="class") rather than wrapping the div around the tr.
You can use the rails content_tag_for to generate this:
<% #departments.each do |department| %>
<%= content_tag_for(:tr, department, :class => "test") do %>
<td class="indexc1">
<%= department.name %>
</td>
<td class="indexc2">
<%= department.location %>
</td>
<td class="indexc3">
<%= department.date_completed %>
</td>
<td class="indexc4">
<ul class="action">
<li><%= link_to 'Edit Info', edit_department_path(department), :class=>"tlink3" %></li>
<li><%= link_to 'Edit Tasks', department_path(department), :class=>"tlink3" %></li>
<li><%= link_to 'Destroy', department, method: :delete, data: { confirm: 'Are you sure?' }, :class=>"tlink3" %></li>
</ul>
</td>
<% end %>
<% end %>
