Cam, I'm hiding all rows only in anticipation of showing the higher
levels of the tree that is represented by this table. Each row has a
class associated with it that indicates the level which simply has a
left-margin css value associated with it giving the appearance of
subordination in the tree. Essentially, I hide all relevant rows,
then show rows with classes "leveln" where n is incremented in a loop,
so if I select to show only the first 3 levels, I hide all, show
level1, level2, and level3, leaving the rest hidden.
There may be a better way to do it, but that's what I came up with.
As for hiding the tbody, that does not allow me to then show the rows
that I want to be visible, because their parent element is hidden.
