AW: AW: [reportlab-users] setting Style for a Sum in a Table

[reportlab-users@reportlab.com]

its seams to work when setting to the amount of rows -1 .
but i am not sure

# setting Style of the last row in a splitted table on the latest page
self.tStyle.add('BACKGROUND', (0 ,nDataRows-1), ( -1, nDataRows-1),
colors.darkgray)

# setting Style of the last row in a splitted table on each page
self.tStyle.add('BACKGROUND', (0 ,         -1), ( -1,          -1),
colors.darkgray)



regards

Jo

When the split happens the splits are cast adrift; effectively the
splitting table cannot know what the results will be used for.

The first part of a split could be informed that it isn't last, would
that do?

Tables have an overrideable onSplit method

class MyTable(Table):
        def onSplit(self,T):
                if not hasattr(self,'_IAMSPLITTING'):
                        T._splitpart=0
                        self._IAMSPLITTING=1
                else:
                        T._splitpart=1
                        del self._IAMSPLITTING

        def draw(self):
                # _splitpart
                #       None    never was split
                #       0       am the leading part of a split
                #       1       am the last part of a split
                _splitpart = getattr(self,'_splitpart',None)
                #... do stuff with this knowledge
                Table.draw(self)

I'm fairly sure the above would work, but I haven't tested it.
