table header respecting xml structure

Hi all,

I have the following document:
<root>
  <column desc="Col 1"/>
  <column desc="Col 2"/>
  <group desc="More Cols">
    <column desc="Col 1"/>
    <column desc="Col 2"/>
    <group desc="Depth Col">
      <column desc="Col 1"/>
      <column desc="Col 2"/>
    </group>
  </group>
  <column desc="Col 3"/>
  <column desc="Col 4"/>
</root>

and I want to build a table with the header respecting
the document structure, that should look like:

TABLE:
================================================================
        |       |         More Cols            |       |       |
 Col 1  | Col 2 | Col 1  | Col 2 | Depth Col   | Col 3 | Col 4 |
        |       |        |       |Col 1 | Col 2|       |       |
===============================================================|

any sugestion or has done something similar??
