The PDF output clearly shows a bug.  For a cell containing a 
paragraph, if the content has some characteristic, then the cell
contents pop several inches outside of the table.

Look again at this PDF.  The text "strange" at the /bottom/ is 
from table #2.  That's about five inches away!  Surely no one 
has any reason to expect that behavior.
