If you click an entry in the admin column you will get the frontend view of this post. I think it should be better if it links to the edit page of the related post. For some reasons it could also be a good option to show only the post-name withaout any link:
'admin_column' => array(
'position' => 'after title',
'title' => 'Column Title',
'link' => 'edit / show / false',
),
