Buttons copy/csv/excel/print only page data

emeg

Hello, I'm trying to use buttons to export all the data but I get only data from the page I see (10 over 16 rows). This is an excerpt from my JS file:

var dataTable = $('#user_data').DataTable({
    language: {
        url:    "//cdn.datatables.net/plug-ins/1.10.18/i18n/Italian.json",
    },
    autoWidth: false,
    dom: 'Bfrtip',
    buttons: [
        {
            extend: 'copy',
            text: 'Copia',
        },
        'csv',
        'excel',
        'pdf',
        {
            extend: 'print',
            text: 'Stampa',
            autoPrint: false
        },
        {
            extend: 'colvis',
            text: 'Colonne',
            postfixButtons: [ 'colvisRestore' ]
        }
    ],
    processing:true,
    serverSide:true,
    order:[],
    paging: true,
    ajax:{
        url:"fetch.php",
        type:"POST"
    }
})

Cuold you help me?
Thanks
