C#/Javascript数据表导出为Excel和PDF

我从一位前同事那里接手了一个C#实体框架项目。他用我不熟悉的方式用Javascript设置了几个表。我需要将这个数据表的内容导出到Excel和PDF文件中（每个文件都有单独的按钮）。我对使用C#、Javascript或JQuery持开放态度。

我最近一直在做ColdFusion，几乎一年都没有看过任何与.NET相关的东西，所以我正在努力复习，并找出我以前从未见过的东西，这让我头脑发热。

用于填充数据表的Javascript代码：

              $(document).ready(function () {
                  var active = true;
                  GetList(active);
              });
              function ChangeList() 
              {
                  GetList($("#ddlRiderType").val());
              }
              function GetList(isActive) {
                  $('#dataTable').dataTable({
                      "sDom": '<"top"lf>rt<"bottom"ip><"clear">',
                      "bAutoWidth": false,
                      "bProcessing": true,
                      "bSort": true,
                      "bDestroy": true,
                      "sPaginationType": "full_numbers",
                      "bServerSide": true,

                      "fnServerData": function (sSource, aoData, fnCallback) {
                          var jsonData = "{jsonAOData : '" + JSON.stringify(aoData) + "', isActive: '" + isActive + "'}";
                          $.ajax({
                              //dataType: 'json', 
                              contentType: "application/json; charset=utf-8",
                              type: "POST",
                              url: sSource,
                              data: jsonData,
                              complete: function () { Init(); },
                              success: function (msg) {
                                  if (msg.d != null)
                                      fnCallback(msg.d);
                              },
                              error: function (XMLHttpRequest, textStatus, errorThrown) {
                                  ntfy_push("Error", ServerFail());

用于标题的数据表

<table id = "dataTable">
<thead>
    <tr>
        <th>Instructor ID</th>
        <th>First Name</th>
        <th>Last Name</th>
        <th>Admin</th>
        <th>Work Phone</th>
        <th>Alt Phone</th>
        <th>Cell Phone</th>
        <th>Email Address</th>
        <th>Rider Coach</th>
        <th>Range Aid</th>
        <th>Organ</th>
        <th>Senior Inst</th>
        <th>Date Added</th>
        <th>Date Modified</th>
        <th>Mod By</th>
        <th>Active</th>
        <th></th>
    </tr>

<tbody></tbody>
