I collect an array of rows because I want to do row.show()/row.hide()
later on in the code. I thought the code would look cleaner this way
as oppose to doing cell.up('tr').show()/hide().
And I tried using #down() and #firstDescendant() instead of
#childNodes[0] but I always get a "...has no properties" message
whenever I do. I'm running Firefox 2.0 on Ubuntu.
