这在我当前的项目中:

var table = $('#listaDocumentos').DataTable({
    dom: 'Bfrtip',
    buttons: [
        'copy', 'csv', 'excel', 'pdf'
    ],
    language: {
        "decimal": "",
        "emptyTable": "No hay información",
        "info": "Mostrando _START_ a _END_ de _TOTAL_ Documentos",
        "infoEmpty": "Mostrando 0 to 0 of 0 Documentos",
        "infoFiltered": "(Filtrado de _MAX_ total entradas)",
        "infoPostFix": "",
        "thousands": ",",
        "lengthMenu": "Mostrar _MENU_ Documentos",
        "loadingRecords": "Cargando...",
        "processing": "Procesando...",
        "search": "Buscar:",
        "zeroRecords": "Sin resultados encontrados",
        "paginate": {
            "first": "Primero",
            "last": "Ultimo",
            "next": "Siguiente",
            "previous": "Anterior"
        }
    }
});

要将“导出”按钮放入下拉列表中，您可以使用以下代码。在初始化数据表时，您可以使用以下代码来显示带有按钮集合的按钮。

buttons: [
                {
                    extend: 'collection',
                    text: 'Export',
                    buttons: [
                        'copy',
                        'excel',
                        'csv',
                        'pdf',
                        'print'
                    ]
                }
            ]

您必须按照以下顺序使用脚本

            buttons: [
                {
                    extend: 'collection',
                    text: 'Export',
                    buttons: [
                        'copy',
                        'excel',
                        'csv',
                        'pdf',
                        'print'
                    ]
                }
            ],
            language: {
                "decimal": "",
                "emptyTable": "No hay información",
                "info": "Mostrando _START_ a _END_ de _TOTAL_ Documentos",
                "infoEmpty": "Mostrando 0 to 0 of 0 Documentos",
                "infoFiltered": "(Filtrado de _MAX_ total entradas)",
                "infoPostFix": "",
                "thousands": ",",
                "lengthMenu": "Mostrar _MENU_ Documentos",
                "loadingRecords": "Cargando...",
                "processing": "Procesando...",
                "search": "Buscar:",
                "zeroRecords": "Sin resultados encontrados",
                "paginate": {
                    "first": "Primero",
                    "last": "Ultimo",
                    "next": "Siguiente",
                    "previous": "Anterior"
                }
            }
        });
    });
</script>
