Sorry, that's the answer to a slightly different question - but one 
that's often useful in this kind of situation.

For your problem I'd be inclined to use sibling recursion:

<xsl:template match="row">
<xsl:apply-templates select="cell[1]" mode="add-missing-cells">
<xsl:wirh-param name="present-in-output select="0"/>
</xsl:apply-templates>
</xsl:template>

<xsl:template match="cell" mode="add-missing-cells" priority="1">
<xsl:with-param name="present-in-output" as="xs:integer"/>
<xsl:copy-of select="."/>
<xsl:apply-templates select="following-sibling::cell[1]" 
mode="add-missing-cells">
<xsl:with-param name="present-in-output select="$present-in-output+1"/>
</xsl:apply-templates>
</xsl:template>

<xsl:template match="cell[@index]" mode="add-missing-cells" priority="2">
<xsl:wirh-param name="present-in-output" as="xs:integer"/>
<xsl:variable name="missing" select="@index - ($present-in-output + 1)" 
as="xs:integer"/>
<xsl:for-each select="1 to $missing"><cell/></xsl:for-each>
<xsl:copy-of select="."/>
<xsl:apply-templates select="following-sibling::cell[1]" 
mode="add-missing-cells">
<xsl:with-param name="present-in-output 
select="$present-in-output+$missing+1"/>
</xsl:apply-templates>
</xsl:template>
