Current behavior
DataTable correctly indicates initial sortField and sortOrder in header: "num" descending here. But the actual data is not sorted, the numbers are ascending:

This happens for both sortField or sortFunction.
But if you do

const [sortField, setSortField] = useState<string>("attributes.num");

 `field="attributes.num"

then you'd see that DataTable does in fact sort data initially, just ignoring sortField/sortFunction. This is especially painful, since it makes it harder to work around the problem by presorting the data yourself.

Expected behavior
DataTable should consult sortField/sortFunction.
You could click the "num" header twice, toggling the sortOrder, resorting the data. Then you'd see the correctly sorted data, as it should be after the initial render:

I was still running into this issue in version 8.2.0. I just submitted #3060, which I believe fixes the issue.
