Ok, my data come from one column of a database, this is what I call
monolithic: only one big block of text.

Everything is transformed into a Paragraph and these Paragraphs goes
into Table cells with multiple columns.

Actually, at this time I use a kinda dictionary to store my test
data and simulate the DB read:
	self.cieInfo = Storage(
	    cial = "My Name", adr2 = "Bergamotte Straße 12", etc...
and
        self.docLines = []
        self.docLines.append( Storage( code=u"CAREFTP6", des=u"Câble réseau cat. FTP 6",
            desl=None, desl_print=False, comment=None, 
            unit_price=Decimal('1.20'), unit=u"ml", qty=Decimal('3.00'), rebate=Decimal('0.0000'),
            total_price=Decimal('3.60'), vatc=1 ) )
	.....

In method, I do something like:
            de = self.docLines[i].des
            dl = self.docLines[i].desl
            dp = self.docLines[i].desl_print
            co = self.docLines[i].comment
            c1 = []
            if de is not None:
                des = Paragraph(de, docItemListCol1des)
                c1.append(des)
                if dp:
                    if dl is not None:
                        desl = Paragraph(dl, docItemListCol1desl, bulletText="©")
                        c1.append(desl)
......
        ilt = Table( self.items_list, [ ITEMS_COL0_W, ITEMS_COL1_W, ITEMS_COL2_W, ITEMS_COL3_W, ITEMS_COL4_W,
                             ITEMS_COL5_W, ITEMS_COL6_W, ITEMS_COL7_W ] )
        # NB: As we pile Paragraphs and not strings, the alignment
        #     that works is into the Paragraphs styles, NOT here!
        ilt.setStyle(TableStyle([('VALIGN',        (0, 0), (-1, -1), 'TOP'), # ALL
                                 ('LEFTPADDING',   (0, 0), (-1, -1), 2), # ALL
                                 ('RIGHTPADDING',  (0, 0), (-1, -1), 2), # ALL
                                 ('TOPPADDING',    (0, 0), (-1, -1), 0), # ALL
                                 ('BOTTOMPADDING', (0, 0), (-1, -1), 3), # ALL
                                 # Table in enclosed in a box
                                 ('BOX',           (0, 0), (-1, -1),  0.50, colors.black),
                                 # HLine under Titles
                                 ('LINEBELOW',     (0, 0), (-1, 0),   0.50, colors.black),
                                 # Vlines to the right of Each Column (inc. Titles)
                                 #('LINEAFTER',     (0, 0), (-2, -1), 0.05, colors.black),
                                 # Vlines to the right of Titles (only)
                                 #('LINEAFTER',     (0, 0), (-1, 0), 0.05, colors.black),
                                 # Vlines to the right of Items Columns (excl. Titles)
                                 ('LINEAFTER',     (0, 1), (-1, -1), 0.05, colors.black),
                                ]))

What I'd like is (sometimes) to separate large block of text ('des',
'desl' or 'comment') by separating them with at least a line break
avoiding the use of a special char to discriminate them, such as:
if desl.count("…") != 0:
	cut string into multiple strings @ "…"
	make Paragraphs with those strings
	put Paragraphs into Table's cells

If there's no <tag> solution, I'll do it this way.

Bullets would be great, but it failed, even with only one line:
bullet appears BUT text isn't wrap to Table column width (it
overwrites right columns and even get out of page).

I also see there's another Paragraph into lib/para.py which
interest me a lot (for <ul><li>, ...) but it fail to replace
the regular one:(

from reportlab.platypus.para import Para as Paragraph
........
