I found this lurking on the hard drive, I worte it a long time ago and have
not tested it but remember it working sucessfully. It functions by
retrieving the tables one at a time - in the manner described earlier - and
writing them into an ArrayList for later processing which may not be what
you want. The code should, however, point you in the correct direction.
Complie and run it on a test machine to make sure it does what you require
please; remember this was test code I wrote a long time ago and have not
tested recently.

TableCell

//
tables.add(range.getTable(para));
