[reportlab-users] Parsing of <table> & ICU wordWrap

[Buganini]

http://pastebin.com/JuQVrGzC

But I just found two problem:
1. table is double if width < 100mm (line 55)
2. this program dies with following message if fontName is not set (line 51)

Traceback (most recent call last):
  File "table.py", line 63, in <module>
