Check out my table normalization solution:

You would need to add to it to be able to track back from the result
to the source, but that shouldn't be too hard.

Has anyone developed code (preferably XSLT 1.0) that can identify
the physical output column of a cell in the XHTML table model?
I.e., given data like so

    <td rowspan="2">content</td>
    <td colspan="3">content</td>

which produces a table looking something like

  x  x  x  x
  .  x  x  x
  x  .  .  x

be able to calculate that table/tr[2]/td[1] is in column 2 and
table/tr[3]/td[2] is in column 4, etc.?

It's not a simple algorithm to figure out because it must take into
account for a given cell all combinations of @colspan and @rowspan in
preceding cells that interact to affect the position of the current

I can see my way to an XSLT 2.0 solution that would work by creating
pseudo-array variable created via a recursive function (basically an XML
version of the "x . x" picture), but that's not an option in XSLT 1.0.
Ideally I need something that will work with current Web browser XSLT
parsers. (The underlying data I'm working with is actually TEI tables,
but the row/column span semantics are identical to XHTML.)
