Export to Excel Formatting Issue

Hi Chaps,

I have a HTML table of data:

<table border="0" cellpadding="0" cellspacing="0" id="tblrepeat">
  <caption><img src="../Images/invoicing.jpg" border="0" onclick="ExportToExcel()"/></a>
  </caption>
    <tr class="checkpoint" >
      <th class="checkpoint" colspan="5">Project / Document</th>
      <th class="checkpoint" colspan="4">Analysis</th>
      <th class="checkpoint" colspan="3">Costing / Discount</th>
    </tr>
    <tr>
      <th height="21">Project No.</th>
      <th>Project Title</th>
      <th>Druck-NR</th>
      <th>Type</th>
      <th>Deadline</th>
      <th>Total</th>
      <th>Full</th>
      <th>Fuzzy</th>
      <th>Proof</th>
      <th>Full Price</th>
      <th>Discount Price</th>
      <th>Total</th>
      </tr>
      	  	        <tr>
        <td>3614</td>
        <td>A_581_5681842_en_GB</td>

        <td>40</td>
        <td>20</td>
        <td>10</td>
        <td>€ 11.90</td>
        <td>€ 2.30</td>
        <td>€ 9.60</td>
      </tr>
            <tr>
        <td>3611</td>
        <td>A_578_5811437_en_GB</td>
        <td>234</td>

        <td>€ 2.30</td>
        <td>€ 9.60</td>
      </tr>
            <tr>
        <td colspan="12">&nbsp;</td>
      </tr>
      <tr>
        <td>&nbsp;</td>
        <td>&nbsp;</td>
        <td>&nbsp;</td>
        <td>&nbsp;</td>
        <td><div align="right"><span class="blueBold">Totals:</span></div></td>
        <td><span class="blueBold">140</span></td>
        <td><span class="blueBold">80</span></td>
        <td><span class="blueBold">40</span></td>
        <td><span class="blueBold">20</span></td>
        <td><span class="blueBold">€ 23.80</span></td>
        <td><span class="blueBold">€ 4.60</span></td>
        <td><span class="blueBold">€ 19.20</span></td>
       </tr>
         </table>

HTML:

And I have a Javascript function, that exports the data to an Excel Spreadsheet:

<script language="javascript" type="text/javascript">  
function ExportToExcel() {
	input_box=confirm("Export to Microsoft Excel?");
		if (input_box==true) {
			var xlApp = new ActiveXObject("Excel.Application");
			// Silent-mode:
			xlApp.Visible = true;
			xlApp.DisplayAlerts = false;
			var xlBook = xlApp.Workbooks.Add();
			xlBook.worksheets("Sheet1").activate;
			var XlSheet = xlBook.activeSheet;
			XlSheet.Name="JavaScript Export to Excel";
			// Store the sheet header names in an array
			var rows = tblrepeat.getElementsByTagName("tr");
			var columns = tblrepeat.getElementsByTagName("th");
			var data = tblrepeat.getElementsByTagName("td");
  			// Set Excel Column Headers and formatting from array
			for(i=0;i<columns.length;i++){
	   			XlSheet.cells(1,i+1).value= columns[i].innerText; //XlSheetHeader[i];
	   			XlSheet.cells(1,i+1).font.color="6";
	   			XlSheet.cells(1,i+1).font.bold="true";
	   			XlSheet.cells(1,i+1).interior.colorindex="45";
			}
			//run over the dynamic result table and pull out the values and insert into corresponding Excel cells
			var d = 0;
			for (r=2;r<rows.length+1;r++) { // start at row 2 as we've added in headers - so also add in another row!
				for (c=1;c<columns.length+1;c++) {
					XlSheet.cells(r,c).value = data[d].innerText;
					d = d + 1;
				}
			}
			//autofit the columns
			XlSheet.columns.autofit;
			// Make visible:
			xlApp.visible = true;
			xlApp.DisplayAlerts = true;
			CollectGarbage();
			//xlApp.Quit();
		}
}
</script>

Code (markup):

The problem is that the Excel Spreadsheet formatting doesn't match the HTML format.
HTML:


EXCEL:


Is there:
a. any way to match the layout?
b. add company logo and/or address in the javascript, so it appears in the Excel Spreadsheet?
