Excel don't "get" the width attribute

[motil]

Hi all,

I'm translating my html report to Excel in the old fashion way

 Response.AddHeader("Content-Disposition", "attachment;filename=report.xls");
 Response.ContentType = "application/vnd.ms-excel";

everything works fine but the excel ignores the "width" attributes and also the cellpadding and cellspacing... I did the same thing before using ASP CLASSIC and i didn't this problem...
any advice, idea, thought will be highly appreciated!

Thanks!
