[reportlab-users] Table, SPAN and splitlast

[Brandon Rich]

Thank you Robin.  On that same note then however, is there a way to get
the last row of the table to have a background?  Much like the
previously talked about issue, I want to have the last row of a table
have a grey background, but when the table spans over two pages, the
grey background is placed on the last row of the previous page, as well
as the last row of the end of the table.  Any suggestions?

Thanks

yes well a line is not the same as a span. The problem here is that the 
splitlast row is always in the first table and the -1 element will
always be in 
the second (assuming that a split occurs). If a split doesn't occur
splitlast is 
not relevant if it does the span is impossible. I don't think we can do
the 
determination of splitlast before the spans are calculated and making a
span a 
function of splitlast is liable to cause some major headaches.
