Data Table Sort Feature

HI All,
Can someone test with a screen reader and determine if it announces the
sort state of the active column header:
http://www.datatables.net/examples/basic_init/scroll_y.html#

I get the following results:
>JAWS 13 and IE9 convey that headers are sortable but do not announce the
states (ascending / descending) once invoked. Note that the active
state gets announced on tabbing and then shift tabbing back.
>NVDA does not announce the headers.
Would be nice to see additional test results.
Thanks,
Devarshi
