A more than decade ago I was tasked to implement a table view in web application (it was time when jQuery was not yet popular, all the hype were DHTML and AJAX). The task was: "do something resembling windows file explorer". When I gave the first version to our testers, each and every one of them came with non-overlapping set of features. Some of these features are listed in this article and even more. If you look into details, you will be amazed how many features there are in such common and simply-looking interface element. It took me (and the testing team) more than a couple of weeks to "kind-a finish" this work.
