Re: [docbook-apps] Centering Tables in Print with Fop 1.0

[deannelson <deannelson@aol.com>]

Here is an adjusted version that triggers only when "align" is used on the table. This has some peculiarities when processed with FOP 1.0.

 

I would suggest that you use fixed column widths and not proportional in the XML tables because proportional is not quite right in FOP when used in a table in a table. But if you use fixed widths it should be fine (or at least in my setup it was).

 

Cheers,

I have no problems now for tables spanning the print width, nor with
tables of any width in html.  But I need to center
less-than-page-width tables in print.

I have used Bob Stayton's xsl fo chunk on p. 474 as a start to try to
get my narrow tables centered in print.  Here is my current version:

<!-- center tables in print, from p. 474 in Stayton: -->
<xsl:template name="table.layout">
 <xsl:param name="table.content"/>
 <fo:table width="100%" table-layout="fixed"><!-- I dded table-layout
attribute -->

   <fo:table-column column-width="proportional-column-width(1)"/>
   <!-  [1] hack next line: added actual table width here -->
   <fo:table-column column-width="3in"/>
   <fo:table-column column-width="proportional-column-width(1)"/>
   <fo:table-body start-indent="0pt">
&n bsp;    <fo:table-row>

       <!-- <fo:table-cell/> -->
       <!-- [2] fo complains about missing table-cell children, I
added Bob's zero space char from p. 261 -->
       <fo:table-cell><fo:block>&#xFEFF;</fo:block></fo:table-cell>

       <fo:table-cell>

         <fo:table>
           <fo:table-body start-indent="0pt">
             <fo:table-row><fo:table-cell><fo:block>
               <xsl:copy-of select="$table.content"/>
              </fo:block></fo:table-cell></fo:table-row>
           </fo:table-body>
  &nbs p;      </fo:table>

       </fo:table-cell>

       <!-- ditto from [2] -->
       <fo:table-cell><fo:block>&#xFEFF;</fo:block></fo:table-cell>

     </fo:table-row>
   </fo:table-body>
 </fo:table>
</xsl:template>

That works for the one specific table when I hardwire the actual table
width.  Is there any xsl:fo magic that can get the total original
table width at [1]?  If not I suppose I can post process the fo to fix
it, but there  must be a more elegant way.

Thanks,
