<description>
In an environment where the data shown in the table can be updated at the server-side, it is often useful to be able to reload the table, showing the latest data. This method provides exactly that ability, making an Ajax request to the already defined URL (use `dt-api ajax.url()` if you need to alter the URL).

<example title="Reload the table data every 30 seconds (paging reset)"><![CDATA[
var table = $('#example').DataTable( {
ajax: "data.json"
} );
setInterval( function () {
table.ajax.reload();
}, 30000 );

<example title="Reload the table data every 30 seconds (paging retained)"><![CDATA[
var table = $('#example').DataTable( {
ajax: "data.json"
} );
setInterval( function () {
table.ajax.reload( null, false ); // user paging is not reset on reload
}, 30000 );
]]></example>
<example title="Use the callback to update an external elements"><![CDATA[
var table = $('#example').DataTable();
table.ajax.reload( function ( json ) {
$('#myInput').val( json.lastInput );
} );
]]></example>
