Hello all,
I try to plot a table on a canvas with the Table module, but it cries for an 
unexisting method :-(
My code :
####################################
from reportlab.pdfgen import canvas
from reportlab.platypus import Table, TableStyle
from reportlab.lib.pagesizes import A4
from reportlab.lib.colors import green, orange, red, black

def box(c, h, a, d):
 ''' Presentation des valeurs de hier, aujourdhui et demain'''
 data =  [["hier", "aujourd'hui", " demain"],
    [str(h), str(a), str(d)]]
 t = Table(data)
 t.setStyle(TableStyle([('ALIGN', (0,0), (-1,-1), 'CENTER'),
      ('VALIGN', (0,0), (-1,-1), 'MIDDLE'),
      ('FONT',(0,0), (-1,-1), ('helvetica', 12)),
      ('INNERGRID', (0,0), (-1,-1), 1, black),
      ('BOX', (0,0), (-1,-1), 2, black)]))
 t.drawOn(c, 100,100)

c=canvas.Canvas("test.pdf", pagesize=A4)
box(c,5,6,7)
c.showPage()
c.save()
##################################
gives :
