I'll suggest stepping back and reconsider the need for such an
interface. A dialog is meant to work like a pop up i.e. interrupting
the task at hand to display an essential message and request user's
acknowledgement via OK / Cancel button. Another scenario is where a
dialog allows  the user to input  data into a few fields so that the
main task at hand can continue. A data table (simple or irregular /
complex)  is meant to convey data relationships that are a trifle
involved (complex) to be included within a dialog. It requires  an
object of role=table to be embedded inside an object with a
role=dialog. Well one can let imagination loose and have more nested
objects (or widgets, if you prefer) within this construct. Browsers
and assistive technologies will never be up to the challenge of
exposing their structure and relationships reliably in all
circumstances. So assistive technology-support may not be attainable
to be WCAG-2 compliant.
So step back and reconsider if a table really needs to be within a
dialog or some other interface merits consideration in the interests
of simplicity and accessibility if this is indeed the need.
