Is it possible to create and display an ad hoc jQuery UI tooltip, from with a particular TD element's mouseenter eventhandler, conditionally, if the value of the cell is above a certain amount, say? The code would test the cell's value and instantiate and display the tooltip after 500ms had elapsed, and close the tooltip in the mouseleave. By "ad hoc" I mean without having attached the tooltip to a selector in the document.ready section.
EDIT: The reason for my question: is there a significant memory or processing overhead to attaching a tooltip to every cell in a large table, when only a few of the cells would actually meet the conditions where a tooltip would be opened?
