Re: [docbook-apps] Alternate background-color in table columns.

[Bob Stayton <bobs@sagehill.net>]

Hi,
Indeed, the template for table entry is a monster template.  But it 
contains a hook that lets you apply formatting properties without 
needing to copy and modify that big template.  The hook is a call to the 
template named 'table.cell.properties'.  That template can be customized 
to insert properties such as background color.  This section in my book 
describes it in more detail:

http://www.sagehill.net/docbookxsl/PrintTableStyles.html#table.cell.properties

If you copy that template to your customization layer, you can use the 
template param named "col", whose value will be set to 1 for the first 
column cells.

If you only want this for some tables, then you can add a tabstyle 
attribute to the table element, such as tabstyle="firstcolumn".  Then 
you can use this in the 'table.cell.properties' template as follows:

  <!-- add this variable declaration -->
  <xsl:variable name="tabstyle">
    <xsl:call-template name="tabstyle"/>
  </xsl:variable>

  <xsl:choose>
    <xsl:when test="ancestor::tgroup">
      <!-- add the following three lines -->
      <xsl:if test="$tabstyle = 'firstcolumn' and $col = 1">
          <xsl:attribute name="background-color">#BBBBBB</xsl:attribute>
      </xsl:if>
      ...

Let me know if you need more details.
