How do you databind a DataSet to an Excel Worksheet from a VSTO Plugin?

I am pretty sure that the key is a listObject but I cannot figure out how to create one in code.

Here is my Setup:
Visual Studios 2008
Visual Studio Template: Excel 2007 Addin
Code Executed from a UserControl.

So far I have the code calling a webservice and returning a DataSet. I have the populated dataset but cannot get the data from that dataset into the active worksheet.

I have seen a few examples of how to do this but all of them seem to be from a different project type (Excel 2007 workbook from what I can tell) and the same commands do not seem to be available.

If someone could show me some sample code of a Dataset being bound in someway to an excel worksheet it would be greatly appreciated.

Got It, finally after a full day researching just this one item:
http://theengineroom.provoke.co.nz/archive/2007/06/19/how-to-bulk-insert-data-into-an-excel-worksheet-using-c-and-office-12.aspx

Attached is the slightly modified version for those having a simular issue:
/// <summary>
        /// Submits Report and populates Excel with the results.
        /// All parameters should have been validated prior to calling this method.
        /// </summary>
        private void SubmitReport()
        {
            try
            {
                ReportService.ASGReportsServiceClient sc = new ExcelReportPlugin.ReportService.ASGReportsServiceClient();
                ReportService.ReturnCode oReturn = new ExcelReportPlugin.ReportService.ReturnCode();
                DataSet ds = sc.ExecuteReport(ut, SelReport, ref oReturn);
                if (oReturn.Result == ExcelReportPlugin.ReportService.Code.cSuccess)
                {
                    //Bind Dataset to the Active Excel Sheet.
                    Microsoft.Office.Interop.Excel.Worksheet worksheet = (Microsoft.Office.Interop.Excel.Worksheet)Globals.ThisAddIn.Application.ActiveSheet;
                    worksheet.UsedRange.Clear();
                    Microsoft.Office.Interop.Excel.Range rng = AddData(ds.Tables[0], worksheet);
                    Addtable(rng, "ThisIsMyTable");                    
                }
                else
                {
                    throw new Exception(oReturn.Description, oReturn.Exception);
                }
            }
            catch (Exception e) { ExceptionHandler(e); }
        }
        /// <summary>

            //add the columns names from the datatable
            for (int i = 0; i < dataTable.Columns.Count; i++)
            {
