Selectors are fine, hover works just great. hide(0) dies but css("display","none") works quickly. Surprisingly toggle completely fails.
Rather than managing 10000 sets of handlers, I'd handle all the events from the table,
and determine the target cell from there.
Awesome, that's exactly the kind of thinking I like
I was considering placing an absolutely positioned transparent div over the whole table and detecting clicks from that, using the mouse coords to set the hidden checkboxes. The advantage of that is that I could also use it to simulate environmental effects (fog, rain, etc) using semi-transparent pngs.
