surprised we have to query the attribute directly here. should we make a method to expose rowSpan/colSpan?

We do have a method to expose it, and I use it, e.g. cell.ariaRowSpan().

The problem is that on my platform, the attribute should be exposed if the author has provided it. We return a default value of 1 on the spans, and 1 is valid. So it it author provided or set by WebCore?

I could change the return value to 0, as was done with rowcount and colcount, and then modify the platform code. You think I should go that route?

It feels like we should be consistent with that model now (0 is no value provided)

thanks

It turns out 0 is a valid value for authors to provide. Returning -1 is consistent with what we do with ariaRowIndex() and ariaColumnIndex().
