Can you move all these props to object literal and rename a11yProps to cellProps?

Looks like the crux of this fix is to avoid generating sub-optimal React.createElement boilerplate with an added function call and for-loop. But that's not obvious at a glance, and might regress later.

I'd suggest adding a comment about why it's important not to mix inline props and spread props.
