(In reply to comment #4)
> I provided a proposed patch of missing implementation of table-related* functions. Generally it seems not every function could be implemented (example, attributesOfRows, attributesOfColumns, attributesOfHeader). Looks like columns, rows and header are not exposed in ATK so far.

>  accessibility/table-attributes.html
>  accessibility/table-sections.html

I think that's right. Please consider my review below though. Thanks!

This function only works for AtkTable, so I think you can already expect that type as the first parameter and avoid the casts below. Just make sure you check and cast properly to AtkTable at the caller points

Also, I think this is one of those cases where you can use the "move semantics" feature of C++11, which is already supported by Vector through its move contructor Vector(Vector&&). See https://www.webkit.org/blog/3172/webkit-and-cxx11/

I think it's better to put the result of get_n_rows() in a variable and use it in the limit condition in the loop, to avoid too many calls to this function.

> +static void getColumnHeaders(AtkObject* accessible, Vector<AccessibilityUIElement>& columnHeaders)

Same considerations than before here (and in the rest of the patch)

> +        for (int column = 0; column < atk_table_get_n_columns(ATK_TABLE(accessibilityObject)); ++column)
> +            visibleCells.append(uiElement->cellForColumnAndRow(column, row));

Please use braces for the outermost loop. Also, you can store the get_n_rows() and get_n_columns() in variables too here

If the C++11 thing works, this will become one line :)
