The answers posted so far are atrocious, which is what I expected. I understood what you were asking ("has someone created a grid with these features in a well-engineered way?"), but the answerers clearly did not. They understood it as an icanhazpatternz question, and they reached into their Gang of Four book to answer it. For what it's worth, 3rd party companies like Telerik have built grids just like this. It's a non-trivial task to do well. — Robert Harvey 4 mins ago
