I realize that this may seem like a silly request given that CEditableTable already has a render method and exuding HTML for a table row or cell outside the context of a table isn't very useful.
However, in my plug-in I am making an AJAX callback to the server to pull down an additional row to insert into a table that was rendered with CEditableTable.render. It would be handy if I could just generate the HTML for a single row or cell for this purpose.
