Table cell (SPAN) across pagebreak

I have attached a simple example that should explain my larger problem.
I am creating a table, and as I am creating the table I am reducing 
redundancy in the table columns (if the cell above has the same word, leave 
cell empty)

If one table cell is larger than a whole page, ReportLab fails to generate 
the PDF.

On line 28, adjust the span length and you will see what I am talking about.

I have spend some time looking around and this problem seems to have not 
been fixed for a long time.

The workarounds I found seem pretty ugly (making the PDF 1 page, but then 
printing is out of the question)

Anyone have any idea on a fix?

Thanks for reading.
