I tested with a case that table with CSS and no ARIA, and that made the table totally inaccessible by returning no rows. I think in AccessibilityTable::addChildren(), is<AccessibilityTableRow> is using the isTableRow() check. And the addChildren() logic is different from AccessibilityARIAGrid::addChildren(), so I'm little hesitate to break that logic.
