The useList hook fetches a page of data, and you can fetch the next page when the user scrolls to the bottom of the list.useList hook is used to fetch a page of data from the "posts" resource. The state variable is used to keep track of the current page, and it's incremented when the user scrolls to the bottom of the page, triggering a fetch of the next page.useTable hook.
