I think you described it fine. My code is just buggy. Here's a solution. 
But it doesn't "feel" as the correct (i.e., best or xslt-like) solution, 
it perfectly fits the task:

   <xsl:template match="row">
       <entry ie="{
           (entry[1]/para[. != ''] , 
reverse(preceding-sibling::row/entry[1]/para[. != ''])[1])[1]}"
           module="{entry[2]/para}" reference="{entry[3]/para}"
           usage="{entry[4]/para}"/>
   </xsl:template>

It will output the following:

<table>
  <entry ie="Col1 A" module="Col2 A" reference="" usage=""/>
  <entry ie="Col1 A" module="Col2 B" reference="" usage=""/>
  <entry ie="Col1 A" module="Col2 C" reference="" usage=""/>
  <entry ie="Col1 D" module="Col2 D" reference="" usage=""/>
  <entry ie="Col1 E" module="Col2 E" reference="" usage=""/>
  <entry ie="Col1 E" module="Col2 F" reference="" usage=""/>
  <entry ie="Col1 E" module="Col2 G" reference="" usage=""/>
</table>


That's the problem with document order. Most of the times that does 
precisely what you want, but sometimes you want it the other way. Hence 
the reverse() keyword.

And I just found out that Saxon (i.e., Java JVM) easily does https. All 
I did was replacing the previous variable I had with a reference to your 
document online. Now is this versatile or what!

<xsl:variable name="input" 
select="document('https://gdcm.svn.sourceforge.net/svnroot/gdcm/Sandbox/xslt/dummy.xml')" 
/>

Don't you just love XSLT / XPath!  :D
