Hi
I need to create a style for tr elements that it paints tr
backgrounds on
different colors depending on its positions.
On the one hand, this is problematic, since there is no mechanism in
XSL-FO that allows you to do that, but...
There is a chance this can be done in XSLT, since depending on the
data, it may be possible to vary the table-row's background-color
according to the position of the nodes in the source tree.
Say, if you have <datarow> elements, and each of those generates a
separate table-row, you could do something like:
<for-each select="datarow">
<fo:table-row>
<xsl:attribute name="background-color">
<xsl:variable name="checkpos" select="position() mod 4" />
<xsl:choose>
<!-- grey background for cells n+3 and n+4 -->
<xsl:when test="(checkpos = 0) or (checkpos = 3)">#F0F0F0</
xsl:when>
<!-- white background otherwise -->
<xsl:otherwise>#FFFFFF</xsl:otherwise>
</xsl:choose>
</xsl:attribute>
<!-- rest of processing -->
</fo:table-row>
</xsl:for-each>
HTH!
Cheers
