two queries would be easier but obviously has a bigger overhead.
You could do the following:
Set $CurrentYear as the yearID from the first row
on each time through the loop, check YearID against $CurrentYear and if
it is not the same then end the table and start a new one before
setting $CurrentYear to the yearID of the current row.
