Another drawback is if you wish to place two twospans on top of each
other. :-( So something more might still be required.

I definitely agree on this.

I loses some of the properties I believe, but I see no reason why it
couldn't retain them. In other words, it's not feature complete. A version
experience quite a bit. For instance, it's very cool how the google
calendar allows you to just click in a cell and start writing.

I like this version, but it's probably not so easy to understand. However,
prefixing each line with '||' is a bit of a annoyance -- it's no longer
possible to just paste the table from an external source.

That's certainly a problem. I have no answer, but maybe could
be used to mark an empty cell?
Having written some posts on this subject now, I think I'm leaning towards
* Add mechanism to convert between different types of table markup styles.
* Aim for a reasonable table editor in the core. It's important that
the editor doesn't destory parts of the table markup that it doesn't
recognice. It'd be ok if it can only work with (:table:) if it's
possible to convert.
* Add mechanism to control alignment on a column basis. This is
for ||...||-tables as well. If cells in the table need a different
alignement, this should be done with e.g. %left% in the cell.
