Re: [docbook-apps] setting a particular table's column widths with xsl

["Bob Stayton" <bobs@sagehill.net>]

Hi Matt,
The stylesheets call a template named 'generate.colgroup', which recursively passes 
through the columns and calls a template named 'generate.col' for each column of the 
table.  The 'generate.col' template outputs one fo:table-column element, normally 
using the width information provided by the XML input.

You could customize the 'generate.colgroup' template from fo/table.xsl to first 
compute the tabstyle using this utility template included in DocBook XSL:

<xsl:variable name="tabstyle">
  <xsl:call-template name="tabstyle"/>
</xsl:variable>

Then customize 'generate.colgroup' to add an xsl:when statement for your custom 
tabstyle value to output the set of four fo:table-column elements for your special 
tables, instead of calling 'generate.col'.

Or you could customize 'generate.col' to handle each column separately based on the 
tabstyle value it computes.
