how to change the entries size by 15,30, 50, and all

Answer 1

[...Array(countPages).keys()].map(num => <button key={num}
className={page === num ? "selected" : ""}
 onClick={() => setPage(num)}>{num + 1}</button>)

Answer 2

just use lengthMenu configuration to set custom page sizes

var table = $("#example").DataTable({
    lengthMenu: [[15, 30, 50, 100], [15, 30, 50, 100]],
    initComplete: function () {
       ...
        } );
     });
