I did something similar in the past, to extend advanced
table markup so that it can produce <th> as well as <td>.

In your case, there appear to be a couple of challenges:

- ensuring the head is at the start of the table
- closing the head when you start the body
- closing the body when you end the table

"Choosing good markup is the hardest task" -- Pm

The "natural" markup might be:

Start a table with (:tablehead:) instead of (:table:)
and start the body with (:bodycellnr:)

Then the additional logic in the table processing function is:

- (:tablehead:) generates a table opening block of
  <table $tattr><thead><tr><td $attr> and a closing block
  of </td></tr></tbody></table>

- (:bodycellnr:) generates a row opening block of
  </td></tr></thead><tbody><tr><td $attr>

Then you'll need to redefine the table markup:

    Markup('table', '<block',
      '/^\\(:(table(?:head|end)?|cell|(?:body)?cellnr|div\\d*(?:end)?)(\\s.*?)?:\\)/ie',
      "CellsWithHeadAndBody('$1',PSS('$2'))");

Writing the CellsWithHeadAndBody function shouldn't be 
too difficult. You might find this PublishPDF recipe
helpful:
http://www.wikipublisher.org/wiki/index.php?n=Cookbook.AdvancedTableHeads

Have a look at the table.php script there.

The one obvious trap is if an author uses more than one
(:bodycellnr:) directive. However, since you say you will 
be using pagelist output, you can make sure it issues
just the one. I dare say it would be possible to add
a check to see whether <tbody> is open.

Hope this helps.
