It was intended. Whether it is desired or not, I am not 100% sure. I'm 
open to alternate algorithms.

This would mean having to do a search of every element in the <thead> 
before knowing whether to use it or not. This would be very bad for 
performance. Also, it's unclear to me what you would look for -- colspan 
attributes with values that don't convert to numeric 1?
