I'm having some trouble getting the right column to wrap properly. I want a
table of 2-inch width on the left, and 6-inch width on the right. Here is my
code:

            ...
            self.style = TableStyle([
            ('TOPPADDING', (0, 0), (-1, -1), 0),
            ('BOTTOMPADDING', (0, 0), (-1, -1), 0),
            ('LEADING', (0, 0), (-1, -1), 10),
            ('FONTSIZE', (0, 0), (-1, -1), 10),
            ('ALIGN', (0, 0), (-1, -1), 'LEFT')])

    def addTextAndHeading(self, text, heading):
        # Called thrice for testing the LEADING and PADDING style options
        data = (heading, text), (heading, text), (heading, text)

        self.story.append(Table(data, colWidths=(2 * inch, 6 * inch),
                          style=self.style))

Now, instead of writing the text and headings separately, I write them
together at once in a Table. Though the TableStyle is working well, the
Table is not; the right column is not wrapping its text. I tested it out
with an addTextAndHeading("text"*100, "heading"), but the
texttextexttext[...] runs off the end of the page and doesn't wrap. Since
the right column width is 6 inches, I thought it would wrap after going for
6 inches of text.

How can I get the right column to wrap?
