Kendo UI Grid alternative
There are lots of libraries but I introduce some of them
zinoUI
jQuery EasyUI
jQWidgets
Wijmo
a source for Pros and Cons is : Top 5 jQuery UI Alternatives
All of the above libraries are modular so you can only use the grid.
I don't know is this even alternative for Kendo UI grid but jQuery DataTables plugin is one https://www.datatables.net
It does have paging, sorting, supports almost every datasource and can be themed by Twitter Bootstrap, jQuery UI etc.
