default.table.width — The default width of tables
<xsl:param name="default.table.width"/>
If non-empty, this value will be used for the
width attribute on tables that do not specify an
alternate width (with the
<?dblatex table-width?> processing instruction, or with
the newtbl.autowidth parameter). For more details see
the section called “Table Width” and
the section called “Automatic Column Width”.
