How to make a csv file from the checked rows?

Question

My problem is that I want to export the selected rows in csv format.

Do you know of a JavaScript function that would allow me to do this?

I attach parts of the code and screenshots that illustrate my request.

I initialize a table in my html page with this function :

function constructTableCustomers() {
    var i;
    // tableau datatable
    var sHTML = "";
    sHTML += '<table id="datatable" class="table table-striped table-bordered" style="width:100%">';
    sHTML += "<thead>";
    sHTML += "<tr>";
    sHTML += '<th style="text-align:center;"><input type="checkbox" id="bulk_action_select_all" onclick="selectAllCustomers()"></th>';
    sHTML += "<th>ID CLIENT </th>";
    sHTML += "<th style='padding-right: 15px !important;'>EMAIL CLIENT</th>";
    sHTML += "<th>ID PRODUIT</th>";
    sHTML += "<th>NOM PRODUIT</th>";
    sHTML += "<th>ATTRIBUT</th>";
    sHTML += "<th>ID ATTRIBUT</th>";
    sHTML += "<th>NOM</th>";
    sHTML += "<th>PRENOM</th>";
    sHTML += "<th>DATE DE CREATION</th>";
    sHTML += "</tr>";
    sHTML += "</thead>";
    sHTML += "<tbody>";

    // pour chaque ligne de résultat, construire la ligne dans datatable
    for(i = 0; i < aOfCustomers.length; i++) {

        sHTML += '<tr style="text-align:center;">';

        sHTML += '<td>' + '<input type="checkbox" id="checkbox_' + i + '">'  + '</td>';

        sHTML += `<td><a href='/${path_admin}/index.php/sell/customers/${aOfCustomers[i]["id_customer"]}/view?_token=${tokenAdminProducts}' target="_blank">${aOfCustomers[i]["id_customer"]}</a></td>`;

        sHTML += `<td><a href='/${path_admin}/index.php/sell/customers/${aOfCustomers[i]["id_customer"]}/view?_token=${tokenAdminProducts}' target="_blank">${aOfCustomers[i]["email"]}</a></td>`;
        
        sHTML += `<td><a href='/${path_admin}/index.php/sell/catalog/products/${aOfCustomers[i]["id_product"]}?_token=${tokenAdminProducts}' target='_blank'>${aOfCustomers[i]["id_product"]}</a></td>`; 
                
        sHTML += "<td>" + aOfCustomers[i]["product_name"] + "</td>";

        sHTML += "<td>" + aOfCustomers[i]["name"] + "</td>";

        sHTML += "<td>" + aOfCustomers[i]["id_product_attribute"] + "</td>";
        
        sHTML += "<td>" + aOfCustomers[i]["lastname"] + "</td>";

        sHTML += "<td>" + aOfCustomers[i]["firstname"] + "</td>";

        sHTML += "<td>" + aOfCustomers[i]["date_creation"] + "</td>";

        sHTML += '</tr>';
    }
    sHTML += "</tbody>";
    sHTML += "</table>";
    $('#customer_mail_alert_stock_table').html(sHTML);
}

thanks in advance !
