Storage sort from DataTable plugin with LocalStorage.

DataTableOrder.js

// Just puting the table element on a variable 
// to not search for the element every time;
let $dataTable = $('#table');

// Get the actual order;
$dataTable.DataTable().order();

// Insert new order;
$dataTable.DataTable().order(/* params... */);

// When event is called;
let localStorageObj = JSON.parse(localStorage.getItem('tableOrder') || '{}');
$dataTable.on('order.dt', () => {
  // Put the order in the localStorage using the actual URL;
  localStorageObj[window.location.href] = $dataTable.DataTable().order()[0];
  localStorage.setItem('tableOrder', JSON.stringify(localStorageObj));
});

// Set the order from localStorage to the table order;
if (localStorageObj[window.location.href]) {
  $dataTable.DataTable().order(localStorageObj[window.location.href]).draw();
}
