Re: Adding rowspans to a table

<xsl:stylesheet version="1.0"

   <xsl:copy>
     <xsl:apply-templates select="@*|node()"/>
   </xsl:copy>
 </xsl:template>

 <!-- keep the cell? if so, add rowspan? -->
 <xsl:template match="td">
   <xsl:variable name="position"
                 select="1 + count(preceding-sibling::td)"/>
   <xsl:variable name="cell-above"

   <!-- remove the <td> if it has the same value as the cell above -->

Hi

I have a three row table where each cell will have a numeric value. I
need to compare values from row[1] and row[2] and rowspan where values
match. I then need to do same for row[2] and row[3].

From this:
 ______________
|__|__|__|__|__|
|__|__|__|__|__|
|__|__|__|__|__|

To this:

 ______________
|  |__|__|  |__|
|__|  |__|__|  |
|__|__|__|__|__|

I'm sure someone has had to tackle this problem before. Are there any
stylesheets out there that could help me arrive at a solution?

Thanks.
