I'm curious why you need role caption at all. I assumed that If you
encounter a table then you read its label and use table interface to
navigate it. Do you make something different? For the reference, caption
and summary methods for table were deprecated in IA2 because they dupe
labelledby and describedby relations. In case of ARIA I guess people do

<div role="label" id="label">
<div role="table" aria-labelledby="label">
</div>

Yes but same time you don't argue to have gridrow role. I see having
gridcell is reasonable from spec structure point of view as a host of
aria-selected attribute but I don't see a good reason to have it from
author point of view.
