Sounds good, let's do that instead!

>> +    AXCoreObject* headerObject() override;

This one can't because it can be overridden by AccessibilityARIAGridRow, but I'll mark that one as final.

>> Source/WebCore/accessibility/isolatedtree/AXIsolatedObject.h:167
>> +    String scope() const override { return stringAttributeValue(AXPropertyName::Scope); }
> Can these be final?

Yep, that was an oversight on my part

>> LayoutTests/accessibility/column-header-scope.html:21
>> +	</table>
> Seems like a lot of lines in this test have 8 space indents — I think we've been trying to stick with 4. Also, I think we typically don't indent after the <body>. So like this:
> <body>
> <table>
>     ....
> </table>
> <script>
> ...
> </script>

will update that along with the other style suggestions!
