Hi Bob

Many thanks.  I've tried to implement the FO version (dbfo) but I'm 
doing something wrong.  Here is my version from my customization:

<xsl:template match="row">
   <xsl:param name="spans"/>
   <xsl:variable name="row-height">
     <xsl:if test="processing-instruction('dbfo')">
       <xsl:call-template name="dbfo-attribute">
         <xsl:with-param name="pis" select="processing-instruction('dbfo')"/>
         <xsl:with-param name="attribute" select="'row-height'"/>
       </xsl:call-template>
     </xsl:if>
   </xsl:variable>
   <xsl:variable name="bgcolor">
     etc. etc. no change
</xsl:template>

I suspect I don't understand 'You want to add a "height" property to 
the fo:table-row output, and it needs to have units'

Also, on testing the HTML version I find that there is a minimum row 
height of about 20 pixels, even with an empty row.  Some code below 
to demonstrate with 50, 30 and 10 px row heights.  I'm trying to 
narrow up my empty separator rows to less than 20 px.
