[reportlab-users] Layout Help

Thanks for the response time.  I'm trying to go this route using
.drawOn, and everything works fine, except for tables.

My code looks like this:

        RLmap = Image(mapimg,width=23*inch,height=34*inch)
        RLmap.hAlign = "CENTER"
        RLmap.drawOn(c1,0.5*inch,0.5*inch)
        title1 = Paragraph(title,styleN)
        title2 = Paragraph(compdist,styleN)
        logo = RLImage(logo,width=2.5*inch,height=1.56*inch)
        cols = [3*inch]
        rows = [1.6*inch,0.75*inch,0.75*inch]
        data = [[logo],[title1],[title2]]
        tblock = Table(data,colWidths=cols,rowHeights=rows)
 
tblock.setStyle(TableStyle([('BOX',(0,0),(-1,-1),2,colors.black),
 
('GRID',(0,0),(-1,-1),2,colors.black),
                                      ('ALIGN',(0,0),(-1,-1),'CENTER'),
 
('VALIGN',(0,0),(-1,-1),'MIDDLE')]))
tblock.drawOn(c1,0.5*inch,0.5*inch)
        c1.showPage()


And the error I get is this:

Traceback (most recent call last):
  File "S:\Rob\Python_Scripts\makeRoadBanMaps.py", line 716, in <module>

    colpositions = self._colpositions
AttributeError: Table instance has no attribute '_colpositions'
Can Tables be added using .drawOn? Or is there another way to draw the
table at a specified position?

Thanks,
Rob

Don't use tables at all.  This is not an application where a flowable 
helps you.  Just place the three components directly at their 
appropriate positions.  Put the image down first, then lay the legend 
and title block over the top of it.
