I did almost exactly that to support "proportional style" columns
in formatting results of an arbitrary SQL query in a servlet. I got a
lot of help understanding tables on this list from Karen Lease
last winter. The archives at MARC have that thread at
http://marc.theaimsgroup.com/?l=fop-dev&m=101179308205088&w=2
Now I go to those archives first for my questions. They are
a great asset, for FOP and many other useful applications.
Essentially, I store the width from the ResultSetMetaData in one of the
inputs to my servlet, and calculate the columns width in the xsl with
<xsl:variable name="sum-width">
<xsl:value-of select="sum(/database/report0/report-line[position()
='1']/child::*/@width)" />
</xsl:variable>
and
<fo:table
space-after.optimum="20pt"
width="9.85in"
table-layout="fixed">
<xsl:for-each select="/database/report0/report-line[position()
='1']/child::*" >
<xsl:variable name="pos"><xsl:value-of select="position()"
/></xsl:variable>
<fo:table-column column-width="from-parent('width') * ({@width}
div {$sum-width})" column-number="{$pos}" />
</xsl:for-each>
(Those measurements of 9.85 in. and 20pt. came from trial and error using
US Legal size paper, landscape orientation.)
It's all in FOP and Xalan. I didn't know about JFOR. I need to output PDF,
but something similar may work for you.
I'm sorry for the horrible way I fear that example will be formatted in
email.
HTH,
Joe
