I've taken to typing scores and brief comments into an org table when
grading my students papers.  In order to extract the scores and comments
for each individual student, I use orgtbl-aggregate as follows (the
student's nickname in this case is assumed to be "tophat", and the table
containing all the scores and comments is names "everyone"):

#+BEGIN: aggregate :table "everyone" :cols "Last First Exercise Pts Comments" :cond (equal Nickname "tophat")
#+END

This creates a new table by extracting the Last, First, Exercise, Pts,
and Comments columns (with headers) and only the rows with "tophat" in
the Nickname column.

My problem is that I need to have the following header on each of the
individual tables in order for them to print out properly:

#+ATTR_LATEX: :environment tabularx :width \textwidth :align lllrX

If I start with

#+BEGIN: aggregate :table "everyone" :cols "Last First Exercise Pts Comments" :cond (equal Nickname "tophat")
#+ATTR_LATEX: :environment tabularx :width \textwidth :align lllrX
#+END

then C-c C-c causes the table to appear but the ATTR_LATEX line is wiped
out.  If instead I start with

#+ATTR_LATEX: :environment tabularx :width \textwidth :align lllrX
#+BEGIN: aggregate :table "everyone" :cols "Last First Exercise Pts Comments" :cond (equal Nickname "tophat")
#+END

then the #+ATTR_LATEX: line is ignored in exporting.

I've been manually pasting the #+ATTR_LATEX: in after extracting the
tables, but there must be a better way to do this.  Any advice will be
appreciated.

FWIW, I realize that I probably don't need orgtbl-aggregate for
this. Also, my ideal solution would be to auto-generate the sub-tables
by looping over the nicknames, simultaneously inserting a section header
with the student's name before each sub-table and a "#+LATEX: \newpage"
line after.  Hints along these lines would be welcome.
