How to export only selected rows

Capamania

How can I export only the selected rows? In my case all visible rows gets exported. In addition, how can I change e.g. the font-size of the exported data?

$(document).ready(function() {
       var dataTable = $('#example').DataTable( {
                    dom: 'Blfrtip',
                    select: {
                        style: 'multi',
                        },
                    buttons: [
                        'colvis',
                        'selectAll',
                        'selectNone',
                        {   extend: 'collection',
                            text: 'Export',
                            buttons: ['copy', 'csv', 'excel', 'pdf', 'print']
                        }
                    ]
        } );
} );

Unfortunately it's not working. What did I do wrong? This is what I tried ...

 $(document).ready(function() {
                var dataTable = $('#example').DataTable( {
                    dom: 'Blfrtip',
                    select: {
                        style: 'multi'
                        },
                    buttons: [
                        'colvis',
                        'selectAll',
                        'selectNone',
                        {   extend: 'collection',
                            text: 'Export Selected',
                            buttons: ['copy','csv','excel','pdf','print'],
                            exportOptions: {
                                rows: { selected: true }
                            }
                        }
                    ],
                    "lengthMenu": [50, 100, 200]
                } );
  } );
