   Thanks, Tim. What I did over the weekend was to use platypus for this one
report.

   I extract a tuple of strings from the database table row (there's only 1
row in this table), and make a list of lables (one for each string). The
platypus table data is:

    tabData = [[labName[0],strings_tuple[0]],
                [labName[1],strings_tuple[1]],
                [labName[2],strings_tuple[2]],
                [labName[3],strings_tuple[3]],
                [labName[4],strings_tuple[4]],
                [labName[5],strings_tuple[5]],
                [labName[6],strings_tuple[6]],
                [labName[7],strings_tuple[7]]]

     t = Table(tabData)
     t.setStyle(tstyle)

where strings_tuple[1] has variable length.

   If col_width and col_height are not explicit in the Table creation, can I
assume that a long string will wrap without running off the right margin of
the page? Or, should I expliticaly set the width and let the height float to
accommodate a long string?
