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.
