Help generate dynamic table in xslt for apache FOP

Question

down vote favorite
For the following xml file, i need to generate an xsl-fo file to be converted into pdf.
I am new to style sheets and struggling to create dynamic table. Please help.
Also, the width for each column varies,based on the column.How would i include this into the code?
The Column Headers and Column Values are dynamically populated in the xml file. Below is a sample.
Can anybody please help in generating xsl-fo or xslt code?
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ReportData>
<ColumnHeaders>
<ColumnHeader>
<Name>Col-Header1</Name>
<Width>5</Length>
</ColumnHeader>
<ColumnHeader>
<Name>Col-Header2</Name>
<Width>10</Length>
</ColumnHeader>
<ColumnHeader>
<Name>Col-Header3</Name>
<Width>8</Length>
</ColumnHeader>
</ColumnHeaders>
<Rows>
<Row>
<Column>Row1-Col1</Column>
<Column>Row1-Col2</Column>
<Column>Row1-Col3</Column>
</Row>
<Row>
<Column>Row2-Col1</Column>
<Column>Row2-Col2</Column>
<Column>Row2-Col3</Column>
</Row>
</Rows>
</ReportData>

I did some xsl-fo a few years ago for a project.
It was an invoice generator spawning multiple PDFs out of single XML document generated from the database. Pretty cool stuff but very resource-consuming.
I'm a bit rusty but here's a basic example for a single table, based on your sample data :
XSLT stylesheet :
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format">
  <xsl:output indent="yes"/>
  <xsl:template match="/ReportData">
    <fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
      <fo:layout-master-set>
        <fo:simple-page-master master-name="Main" margin="8mm"
          page-width="250mm"
          page-height="100mm">
          <fo:region-body />
        </fo:simple-page-master>
      </fo:layout-master-set>
      <fo:page-sequence master-reference="Main">
        <fo:flow flow-name="xsl-region-body">
          <fo:block>
            <fo:table table-layout="fixed" border-style="solid">
              <xsl:apply-templates select="ColumnHeaders/ColumnHeader" mode="column"/>
              <xsl:apply-templates select="ColumnHeaders"/>
              <fo:table-body>
                   <xsl:apply-templates select="Rows/Row"/>
              </fo:table-body>
            </fo:table>     
          </fo:block>
        </fo:flow>
      </fo:page-sequence>
    </fo:root>
  </xsl:template>
  <xsl:template match="ColumnHeaders">
    <fo:table-header>
         <fo:table-row background-color="rgb(200,200,200)">
              <xsl:apply-templates select="ColumnHeader" mode="header"/>
         </fo:table-row>
    </fo:table-header>
  </xsl:template>
  <xsl:template match="ColumnHeader" mode="column">
    <fo:table-column column-width="{concat(Width*10,'mm')}"/>
  </xsl:template>
  <xsl:template match="ColumnHeader" mode="header">
    <fo:table-cell border-style="solid">
      <fo:block font-weight="bold"><xsl:value-of select="Name"/></fo:block>
    </fo:table-cell>
  </xsl:template>
  <xsl:template match="Row">
       <fo:table-row>
      <xsl:apply-templates select="Column"/>
    </fo:table-row>
  </xsl:template>
  <xsl:template match="Column">
    <fo:table-cell border-style="solid">
      <fo:block><xsl:value-of select="."/></fo:block>
    </fo:table-cell>
  </xsl:template>
</xsl:stylesheet>

Calling the XSLT engine and FOP :
{code}
D:\XSLT>gen_pdf_otn.bat
D:\XSLT>java -jar saxon9he.jar -s:in/reportdata.xml -xsl:testfo.xsl -o:out/testfo.xml  2>errors.log
D:\XSLT>java -jar fop.jar org.apache.fop.cli.Main -fo out/testfo.xml -pdf out/testfo.pdf -c morefontsconfig.xml  2>errors.log
D:\XSLT>pause
Appuyez sur une touche pour continuer...
{code}
Ouput :
- The intermediate XSL-FO document :
{code:xml}
