Export selected column and without data to excel using angularjs

i want to download excel file from html table and i want to export only selected column and without any data. The ex-cel file should show only the header of the html table without data.

here is my sample jsfiddle.

http://jsfiddle.net/TheSharpieOne/XNVj3/1/

my code

  $scope.exportData = function () {
         var blob = new Blob([document.getElementById('table2excel').innerHTML], {
             type: "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;charset=utf-8"
         });
         saveAs(blob, "Report.xls");
     };

from this fiddle i want only Name and DOB column without data.

Is this is possible to download the excel file.

Thank you.
