[reportlab-users] Table entries with VALIGN=MIDDLE are not correct

[Dirk Holtwick]

Hi,

I think there is still a bug in the vAlign part of cell rendering, 
concerning table cells containing flowables. For me only 
vAlign=="BOTTOM" seems to work. I tried a bit to solve the problem, but 
didn't find a proper solution. The problem seems to have to do with the 
following lines in tables.py:

    def _drawCell(self, cellval, cellstyle, (colpos, rowpos), (colwidth, 
rowheight)):
       [...]
            if valign=='TOP':
                y = rowpos + rowheight - cellstyle.topPadding
            elif valign=='BOTTOM':
                y = rowpos+cellstyle.bottomPadding + h
            else:
                y = 
rowpos+(rowheight+cellstyle.bottomPadding-cellstyle.topPadding+h)/2.0

The value of "rowheight" isn't the value of the maximum rowheight. I 
propose to calculate at first the maximum value of the height of a row 
and then the TOP calculation with y = rowpos + rowheight - 
cellstyle.topPadding should work.

Maybe someone knows how to do this, I failed :-(

Bye,
Yours Dirk
