Javascript Datatables（2.1.4）如何使用aButtons更改csv内容

在我的表格中，有一列值是“google”，当用户单击它时，它将成为指向google网站的链接。但当用户想要导出csv内容时，我想将google值改为链接。目前，csv内容只是谷歌文本

{
      "sExtends": "csv",
      "sButtonText": "export CSV",
      "sCharSet": "utf8",//solve csv chinese encoded problem
      "bBomInc": true,//solve csv chinese encoded problem
      "fnCellRender": function ( sValue, iColumn, nTr, iDataIndex ) {
               if(sValue.toString().match("href")){
                        return $(sValue).attr("href");
               }
               return sValue;
      }//to make some change to the cell content before export the csv
}

如何在“我的按钮”功能中执行此操作？

{
      "sExtends": "csv",
      "sButtonText": "export CSV",
      "sCharSet": "utf8",//solve csv chinese encoded problem
      "bBomInc": true,//solve csv chinese encoded problem
      "fnCellRender": function ( sValue, iColumn, nTr, iDataIndex ) {
               if(sValue.toString().match("href")){
                        return $(sValue).attr("href");
               }
               return sValue;
      }//to make some change to the cell content before export the csv
}

我的代码：

"oTableTools": {
      "sSwfPath": "http://cdn.datatables.net/tabletools/2.2.2/swf/copy_csv_xls_pdf.swf",
      "aButtons": [
          {
            "sExtends": "csv",
            "sButtonText": "export csv",
          }
      ]
}

{
      "sExtends": "csv",
      "sButtonText": "export CSV",
      "sCharSet": "utf8",//solve csv chinese encoded problem
      "bBomInc": true,//solve csv chinese encoded problem
      "fnCellRender": function ( sValue, iColumn, nTr, iDataIndex ) {
               if(sValue.toString().match("href")){
                        return $(sValue).attr("href");
               }
               return sValue;
      }//to make some change to the cell content before export the csv
}

我在aButtons中添加了fnCellRender函数，如下所示，以对csv内容进行一些更改

{
      "sExtends": "csv",
      "sButtonText": "export CSV",
      "sCharSet": "utf8",//solve csv chinese encoded problem
      "bBomInc": true,//solve csv chinese encoded problem
      "fnCellRender": function ( sValue, iColumn, nTr, iDataIndex ) {
               if(sValue.toString().match("href")){
                        return $(sValue).attr("href");
               }
               return sValue;
      }//to make some change to the cell content before export the csv
}
