如何清理此数据表的过滤器头

Question

我有以下代码，将数据加载到数据表中，并通过选择添加了一些过滤器，但是当我创建新的数据表时，该选择在数据表的头部相乘

我已经尝试过使用destroy函数，但是仍然没有结果在头部增加

$("#button_id").click(function(){


var dataSet = [
[ Math.random().toString(36).substring(7), Math.random().toString(36).substring(7), Math.random().toString(36).substring(3), Math.random(), "2011/04/25", "$320,800" ],
   [ Math.random().toString(36).substring(7), Math.random().toString(36).substring(7), Math.random().toString(36).substring(3), Math.random(), "2011/07/25", "$170,800" ]];

if ($.fn.dataTable.isDataTable('#dt_detalle'))
{
    var tables = $('.dataTable').DataTable();
    var table = tables.table('#dt_detalle');
    table.destroy();
    // alert('xx')
}

var op = $("#Txt_OP").val();
let tabla = $("#dt_detalle").DataTable({
    "destroy": true,
    initComplete: function() {
        this.api().columns(".searchable_option").every( function () {
            var column = this;
            var select = $('<br><select class="browser-default" style="width:100%"><option value=""></option></select>')
            .appendTo($(column.header()))
            .on('change', function() {
                var val = $.fn.dataTable.util.escapeRegex(
                    $(this).val()
                );
                column
                .search(val ? '^' + val + '$' : '', true, false)
                .draw();
            });
            
            column.data().unique().sort().each(function(d, j) {
                select.append('<option value="' + d + '">' + d + '</option>')
            });
        });
    },
    "order": [
        [1, "asc"]
    ],
   data: dataSet,
    columns: [
        { title: "Name" },
        { title: "Position" },
        { title: "Office" },
        { title: "Extn." }
    ],
    "select": {
        "style": 'os',
        "items": 'cell'
    }
});
function actualizar() {
    /* Calculamos la suma mediante una función de reducción */
    let suma = tabla.cells( { selected: true } )
    .data()
    .reduce(function (a, b) {
        let x = parseFloat(a) || 0;
        let y = parseFloat(b) || 0;
        return x + y;
    }, 0
);
/* Asignamos al campo del formulario el resultado obtenido */
$('input[name="autosum"]').val(suma);
}

tabla
.on( 'select', actualizar )
.on( 'deselect', actualizar );

});
