Datatable动态导出Excel，IExporterHeaderFilter设置禁用表头筛选器无效

[us12548]

        DataTable dt = new DataTable();
        dt.Columns.Add(new DataColumn("ProductCode", typeof(string)));
        dt.Columns.Add(new DataColumn("ProductName", typeof(string)));
        dt.Columns.Add(new DataColumn("Quantity", typeof(string)));
        for (int i = 0; i < 10; i++)
        {
            var row = dt.NewRow();
            row["ProductCode"] = "ProductCode" + i.ToString();
            row["ProductName"] = "ProductName" + i.ToString();
            row["Quantity"] = "Quantity" + i.ToString();
            dt.Rows.Add(row);
        }
        IExcelExporter excelExporter = new ExcelExporter();
        //设置IExporterHeaderFilter为null无效
        var res = await excelExporter.ExportAsByteArray(dt,null);
        return new FileStreamResult(new MemoryStream(res), "application/octet-stream")
        {
            FileDownloadName = $"{DateTime.Now.ToString("yyyyMMdd")}.xlsx"
        };

还是有筛选器
