docs tbd.

creation hints variant per table happens as follows:

def test_mark_hints_with_variant() -> None:
    @dlt.resource
    def with_table_hints():
        # create variant for table a,  item dispatch to table a
        yield dlt.mark.with_hints(
            {"id": 1, "pk": "A"},
            dlt.mark.make_hints(
                table_name="table_a", columns=[{"name": "id", "data_type": "bigint"}]
            ),
            create_table_variant=True,
        )
     # then you can dispatch subsequent items like
     yield dlt.mark.with_table_name({"id": 4, "pk": "D"}, "table_a")
