Load Html - Save to xls ignoring table formatting

Hi folks,

I have recently replaced the functionality to export html tables to Excel from one that simply set the response’s contentType to excel and then wrote the table to the Response with Apose.Cells. Prior to going the Aspose way the resulting worksheet was formatted as defined in the html table only now I get a worksheet with zero formatting.

Could someone tell me if I am doing something wrong as I am reallllllly close to a deadline and it’s looking like we may not be able to use Aspose. Any suggestions will be appreciated

Please see attached files:
table.txt is a file representation of the html being passed to the workbook constructor.
ResponseWriteResult.xls is the results before switching to Aspose.
AposeResult.xls is the results after switching to Aspose.

Code: (“Content” would be the contents of table.txt which is dynamic dependent upon the table being exported.)

context.HttpContext.Response.Buffer = true;
context.HttpContext.Response.Clear();
context.HttpContext.Response.ClearHeaders();
context.HttpContext.Response.ClearContent();
context.HttpContext.Response.AddHeader(“content-disposition”, “attachment; filename=”" + fileName + “”.xls");
context.HttpContext.Response.ContentType = “application/vnd.ms-excel”;

using (var stream = new MemoryStream(Encoding.ASCII.GetBytes(Content)))
{
var loadOptions = new LoadOptions(LoadFormat.Html)
{
ConvertNumericData = false
};
var workbook = new Workbook(stream, loadOptions);
