Note that my text continues, after the piece quoted above: "with the
same number of items and with some meaningful relationship across the inner
lists so that the n'th items in inner lists have some connection with each
other".
Thus, a table is _more_ than a list of lists, as explained above. We could
also describe this by saying that a table is a list of lists _in two ways_:
a list of rows, which are lists, and a list of columns, which are lists. But
there's still more: the relationship I mentioned above.

If "nested list" means more than a list of lists, then it means a particular
_rendering_ of such a construct. Apparently, for a table, which is _more_
than a list of lists, namely with relationships across the lists, such
rendering is usually not optimal.
