A little off the topic... We have functions
    // FIXME: need to implement cellIndex
    int cellIndex() const { return 0; }
    void setCellIndex(int) { }

in RenderTableCell.h ... Is this still required ? It does seem to be used anywhere...

It was added in 
http://trac.webkit.org/browser/trunk/WebCore/khtml/dom/html_table.h?annotate=blame&rev=4

It also appears we have a RenderTableCell::cellIndex() function which does nothing and probably shoudl be removed.

> Source/WebCore/html/HTMLTableCellElement.cpp:73
> +    int index = -1;
> +    if (!parentElement() || !parentElement()->hasTagName(trTag))
> +        return index;
> +
> +    index = 0;

I would have jsut used "return -1" here, and left int index = 0; as it was.  It saves you a line of typing.

This could read shouldBe("th_with_tbody_parent.cellIndex", "-1");

Thanks!

We don't do K&R style anymore.  This declaration could be inline, right before the for() below, but the patch overall is fine, and clearly the rest of this file needs a style cleanup some day anyway.
