The simple answer is that grids are hard. Everyone loves the simplicity of tabluar, Excel-like data display - yet it's clearly a difficult task to achieve in the browser due to the sheer DOM weight of such widgets. Factor in advanced capabilities like sorting, filtering, customizable display, et al and HTML/JavaScript performance becomes even harder to manage. Sencha's Ext JS framework has had perhaps the industry's best grid widget since 2007. It offers excellent performance, handles infinite data sizes, built-in sorting and filtering, and is completely customizable. If you poke through the Sencha API documentation, you'll see a ton of other features.
