[ePub] - table with css borders

Dear All,

when generating ePub2 output with the following settings:

<xsl:param name="css.decoration" select="1"/>
<xsl:param name="table.borders.with.css" select="1"/>
<xsl:param name="table.frame.border.thickness">1px</xsl:param>
<xsl:param name="table.cell.border.thickness">1px</xsl:param>

my CALS table has incorrectly rendered borders if some cells have the align
attribute specified.

Looking into the generated source HTML code it is clear that initial style
attribute with the border specification is later overwritten with the
text-aling CSS property (instead of merging).

The same settings works fine in case of ePub3.

Has anybody the same experience?

Is this settings even a valid combination?

Thanks, Jan
