.... I guess what David wants to say is :

<table bgcolor="#ff0000">
     <xsl:attribute name="bgcolor">
     <xsl:if test="@col1"><xsl:value-of select="@col1"/></xsl:if>
     </xsl:attribute>
     <tr><td><xsl:apply-templates/></td></tr>
<table>

Only David knows what he wants to say here, because the original 
posting was talking about 3 tables when each table has the 'bgcolor' 
attribute. ( BTW  - <xsl:attribute> is also missing here ).
