Making tables comment-able

@mrjkconnor, you’ll find the parser class in the plugin. It’s called class_commentpress_parser.php. However, I would strongly advise against modifying the core plugin. A simpler way to achieve what you want is to use the <!--commentblock--> quicktag. Place one of those as a separator between every “block” of content that you want to be commentable. These blocks can contain any number of top-level elements but cannot be used to (for example) split lists. Also bear in mind that once there is a <!--commentblock--> quicktag present, automatic parsing does not happen, so you will have to divide the content with quicktags the way you want it.
