Rails 4, add checkbox for each object in a table?

I want to conditionally add a check box to each object in a table, such that, a user can select multiple items. When the user click's submit - I want to change the state of the objects that were selected and update the table via ajax. I've looked at collection_check_boxes but I'm not sure how I can implement it in this situation.

See below, the code I wish to modify - to include the check boxes on each line.

<% if @events != nil %>
    <% @events.each do |event| %>
    <tr>
        <td><%= event.driver.name%></td>
        <td><%= event.name%></td>
        <td><%= event.drop_off? ? "Drop Off At" : "Pick Up From" %></td>
        <td><%= event.location_name%></td>
        <td><%= event.is_game ? "Game" : "Not Game(event, practice)" %></td>
        <td><%= event.location_address %></td>
        <td><%= event.date ? event.date.strftime("%A, %d %b %Y %l:%M %p") : "Please Enter Details on TeamSnap!"%></td>
    </tr>
    <% end %>
<% end %>

I'm a little confused as to how I may implement a form_for in this context...

Any ideas are hugely appreciated!

Thanks!
