        <colspec colwidth="1*"/>
        <colspec colwidth="1*"/>
        <colspec colwidth="1*"/>
        <colspec colwidth="12*"/>
        <colspec colwidth="1*"/>
    </tgroup>
        <thead>
            <row>

Answer 1

That format is not clear to me but perhaps

   <xsl:template match="entry[@namest]">
        <xsl:variable name="col-range" select="@namest/xs:integer(replace(., 'col', '')) to @nameend/xs:integer(replace(., 'col', ''))"/>
        <tr colspan="{$col-range[last()] - $col-range[1] + 1}" width="{sum(ancestor::tgroup/colspec[position() = $col-range]/@colwidth/xs:decimal(translate(., '*', '')))}%">
            <xsl:apply-templates/>
        </tr>
    </xsl:template>

helps.
