I wanted a quick diagnostics page in html / js and this included grid to show server logs, decided to use slickGrid . All pretty easy to use apart from one thing - last column to fill remaining space... Nothing in their examples, so here's one for posterity... Not sure if it's the preferred way, but it works - the most obivous issue for is doing a DOM search to get the Viewport element - this is tightly coupled to the current latest release. Stuck the implmentation in a Class and not provided any logic for creating Data, Columns or other grid optnios / plugins - tried to keep it simple...
