USe Microsoft Primary Interop Libraries for converting DataTable to PDF.

C#

public bool ConvertWordToPdf(object source, object target)
       {
           if (_wordDocument == null)
           {
               _wordDocument = new Microsoft.Office.Interop.Word.ApplicationClass();
           }
           try
           {
             //  wordDocument.Visible = false;
               _wordDocument.Documents.Open(ref source, ref _unknown, ref _unknown, ref _unknown, ref _unknown, ref _unknown, ref _unknown, ref _unknown, ref _unknown, ref _unknown, ref _unknown, ref _unknown, ref _unknown, ref _unknown, ref _unknown, ref _unknown);
              // wordDocument.Application.Visible = false;
               _wordDocument.WindowState = Microsoft.Office.Interop.Word.WdWindowState.wdWindowStateMinimize;
               object format = Microsoft.Office.Interop.Word.WdSaveFormat.wdFormatPDF;
               _wordDocument.ActiveDocument.SaveAs(ref target, ref format, ref _unknown, ref _unknown, ref _unknown, ref _unknown, ref _unknown, ref _unknown, ref _unknown, ref _unknown, ref _unknown, ref _unknown, ref _unknown, ref _unknown, ref _unknown, ref _unknown);
           }
           catch (Exception e)
           {
               Console.WriteLine(e.Message);
           }
           finally
           {
               if (_wordDocument != null)
               {
                   _wordDocument.Documents.Close(ref _unknown, ref _unknown, ref _unknown);
               }
               _wordDocument.Quit(ref _unknown, ref _unknown, ref _unknown);
           }
           return true;
       }

//Use the above function as described below

C#

var obj = new ConvertMethodHelper();
           const string source = @"C:\Test\Prod20131107141635558.doc";
           const string destination = @"C:\Test\word07.pdf";
           bool checkMethodExecStatus=obj.ConvertWordToPdf(source, destination);
