The "edit" link doesn't work. How do I implement that?

Did you get this figured out? If not I’d be glad to help you troubleshoot it.

The column_title function has the actions setup to do it but you’ll need to change the code a little. Are you using a Custom Post Type? Here is what I used to create an edit link. I removed the delete function as it wasn’t necessary for my project, although its a very similar modification.

function column_title($item){

      //Build row actions
      $actions = array(
          'edit'      => sprintf('<a href="/wp-admin/post.php?action=%s&post=%s">Edit</a>','edit',$item['ID']),
      );

      //Return the title contents
      return sprintf('%1$s <span style="color:silver">(event-id:%2$s)</span>%3$s',
          /*$1%s*/ $item['post_title'],
          /*$2%s*/ $item['ID'],
          /*$3%s*/ $this->row_actions($actions)
      );
  }

Let me know if that isn’t clear or if you have any other questions.
