Nit: tables are part of github-flavored markdown, not John Gruber's original Markdown.PL, and there's also another table extension syntax for markdown. Apart from that, the point of markdown is that you can drop to plain inline HTML/markup or markup blocks when markdown short syntax is insufficient, such as for complex table layouts. Regular markdown syntax really is made for plain text editing. As such, it would probably make more sense that a visual editor, cool as it looks, targets robust markup serialization (HTML-in-markdown) rather than producing markup shortform syntax IMO (but then again, the plethora of markdown editors may prove me wrong on this one).
