 ## Sortable with pagination
 
-If you want `DataTable` to sort the whole dataset but still display paginated content, you need to pass the whole dataset in the `rows` prop, 
-and then limit displayed content by using `pageSize` and `page` props, which are corresponding to the same props in the `Pagination` component.
+For pagination, bind to the `pageSize` and `page` props of `Pagination` and pass their values to `DataTable`.
