SlickGrid
A lightning fast JavaScript grid/spreadsheet
Quite simply, SlickGrid is a JavaScript grid/spreadsheet component. It is an advanced component and is going to be a bit more difficult to learn and configure, but once you realize its full potential, it will blow your mind! SlickGrid utilizes virtual rendering to enable you to easily work with hundreds of thousands of items without any drop in performance. In fact, there is no difference in performance between working with a grid with 10 rows versus a 100’000 rows. This is achieved through virtual rendering where only what’s visible on the screen plus a small buffer is rendered. As the user scrolls, DOM nodes are continuously being created and removed. These operations are highly tuned to provide optimal performance under all browsers. The grid also adapts to the direction and speed of scroll to minimize the number of rows that need to be swapped out and to dynamically switch between synchronous and asynchronous rendering. -
