Why can't I use the jQuery Tooltip Plugin on a TR?

I can't use this on a TR, specifically my selector is:

$(".alignment_tr  td:not('.remove-link')")

I am not sure what you mean in your question. TR elements can have events attached to them, so there is theoretically no obstacle to have tooltips attached on them.

Your selector selects td elements. If you want the tr associated, just call .parent().

Alternatively, use :has() :

$(".alignment_tr:has(td:not('.remove-link'))")
