css in cfdocument

Hi

my code below is working fine except the css didn't work if i have scope="row" in report.cfm page.  if  i removed that line, then the front size worked fine, otherwise, it was small.  I always have td scope in the cfm page with css with those style and it worked fine, but don't know if scope has something to do with cfdocument?

thanks

report.cfm

<cfif form.submit neq "">

<cfsavecontent vairable="session.report">

<td scope="row">My Report</td>

</cfsavecontent>

#session.report#

</cfif>

<a href=pdf.cfm">view pdf</a>

<cfset request.theReport = session.report />

<cfdocument format="pdf" orientation="landscape" marginRight=".5" marginLeft=".5">

<style>

body, table, th, td {font: normal normal normal 15px/normal, Arial;

</style>
