I don't have the time for a complete solution, but maybe
this will help: you say say "Therefore, I don't know where
the pagebreak will occur," but that's not entirely true:
the page break occurs when you invoke doc.newPage();
Of course: at that time, your PdfPTable is already constructed,
BUT: you can always add content with ColumnText; you could add
the "name" in this cell with ColumnText instead of PdfPTable.
The only problem you need to overcome to achieve this, is to
find out the coordinate of the upper left cell. I'm not sure
if this will work, but I would try if TableEvents can help me
with this... (I haven't tried this myself, so I apologize in
advance if I'm pointing you in the wrong direction.)
