Use data tables.net into Framework7, Vue and Cordova project

Hello,
it’s possible use the Jquery and dataTabes.net into framework7, Vue and Cordova project?

I try to import jQuery into index.html in this mode:

<script src="https://code.jquery.com/jquery-3.4.1.min.js" integrity="sha256-CSXorXvZcTkaix6Yvo6HppcZGetbYMGWSFlBw8HfCJo=" crossorigin="anonymous"></script>

and test whit this code:

window.onload = function() {
    if (window.jQuery) {
        // jQuery is loaded
        alert("Yeah!");
    } else {
        // jQuery is not loaded
        alert("Doesn't Work");
    }
}

It’s work!!!

If import in the app.js file not work

import JQuery from './js/jquery-3.4.1.min.js';

For local file where i put the file ?

After when try to integrate a datatable i use cdn file:

<link rel="stylesheet" href="https://cdn.datatables.net/1.10.20/css/jquery.dataTables.min.css">
  <script src="https://cdn.datatables.net/1.10.20/js/jquery.dataTables.min.js" ></script>

But, when i try to initialize the datatable i have error.

$(document).ready(function() {
     $('#example').DataTable();
 });

What is the error text?

dataTable is not a function.
I think not have imported correctly a datatable js.
