Complicated lists on the web are really bad. If you have a lazily populated table, it breaks the browser's Find, it typically breaks the scroll bar positioning, there's visible holes while it populates, scrolling is janky slow, the scroll bar will jump unexpectedly. This is one place where HTML does not give enough primitives for a quality library-based solution.
