a numeric filter such as $set[1] is shorthand for the boolean filter
$set[position()=1]
so the above is shorthand fr
<xsl:apply-templates select="$set[postion()=position()]/*"/>
so as the test is always true it is the same as
<xsl:apply-templates select="$set/*"/>

 ./ at the start of an xpath is redundent, so this is the same as

<xsl:apply-templates select="Cell"/>

and selects child Cell elements

You'd need to be clearer about what you mean here.
. or current() will get the current context

perhaps 

select="Cell[count(.|$set)=count($set)]"

is what you need but I can't be sure from this description


> I have created a node set of Rows:
>

you probably don't want // there which causes a search to arbitrary
depth looking for Row elements, but why do you need this variable 
at all, rather than simply applying templates to the Row elements as
they occur in the source?

It would seem that by 


<xsl:template name="Row">
<tr>
 <xsl:param name="set"/>
 <xsl:apply-templates select="$set[postion()]/*"/>
</tr>
<xsl:template>



you want to select the children of _this_ Row, but you don't need to do
anything for that, just



<xsl:template name="Row">
<tr>
 <xsl:apply-templates/>
</tr>
<xsl:template>

would work fine wouldn't it?
