I have got the table generated - however still seeing the message : WooCommerce wp_wc_reserved_stock table creation failed. Does the wp user have CREATE privileges on the wordpress_somedb database?

To my knowledge this happens because these values do not match your environment ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_520_ci;
