Table Head Row Background Color

[Kerstin Buchholz <Leeloo5E@web.de>]

Hello everybody,

I'am using informaltables surrounded by a blockquote for displaying tables in PDF- and HTML-Output.
The informal tables mostly looks like this:
<blockquote>
   <title>Title</title>
       <informaltable>               
                <tgroup cols="4">
                    <thead>
                    <row >
                        <entry align="center">First</entry>
                        <entry align="center">Second</entry>
                        <entry align="center">Third</entry>
                        <entry align="center">Forth</entry>
                    </row>
                    </thead>
                    <tbody>
                        <row><entry>some content</entry></row>
                        <row><entry>some content</entry></row>
                        <row><entry>some content</entry></row>
                        <row><entry>some content</entry></row>                   
                    </tbody>
                </tgroup>
            </informaltable>       
        </blockquote>

I want to set an background-color for <thead> but I only find this http://www.sagehill.net/docbookxsl/BGtableColor.html#TableRowBackground . Its not what needed.

PIs doesn't work, because I generate a DocBook-XML from a XSL. In XSL is set an PI <?dbhtml bgcolor="#EEEEEE" ?>, but this isn't take over to the generated XML.

I find in table.xsl at line 255 the template for thead. But how can I specify the background-color there, so that a normal XML-Parser takes this value in the right way? And how can I specify a background-color for entries without using PIs? I can't find anything special about this problem.

Thank you for your answers.

K.
