first, any control of what part of the markup corresponded to which part of (wikified) html seems to be complicated. For instance, because the table can be transcluded. And also not each pipe symbol divides cells: [[prettyLink|also contains pipe symbols]]; etc. Consistent approach would be changing the wikifier or some other complicated thing, even to understand how the wikifier [1] works is not as simple as one would desire; second, the twve plugin set already implements such stuff, and there's "move colomn to the left/right" and "move raw up/down" options (buttons), so drag&drop "move to an arbitrary position" action shouldn't be difficult to implement. Moreover, Vincent has created the "base" plugin "twve.core" which should ease the access to the markup that corresponds to the generated DOM, and it would be natural to add the "drag&drop sort" functionality to twve.table, so I encourage you to discuss this with Vincent. I could even try to review your code and help with "why it doesn't work" (I haven't understood you idea well from the description), but it seems counter-productive as the functionality you describe sounds natural to add to twve and implementing it in another plugin will quite probably cause conflicts between the two (as both modify tiddler text from the view mode).
