[reportlab-users] splitByRow

ReportLab 2.2
I seem to not understand the splitByRow argument to Table(). If I set it to 0
for a table that is too tall and wide for the page I get the following
traceback. If I set it to 1 then the doc fails to build unless the columns
fit within the page width then the table splits between rows. It seems at
present tables can only split by row, not by column. This is contrary to what
the documentation says;

"For very wide tables, they can also split 'by column'. You can choose whether
tou(sic) want to split down-and-across or across-and-down"

Am I missing something?
