This example show how we can load JSON data from Server. Note that we
we can use a multiple indexes in col model to sort data.

JSON Example

Inv No	Date	Client	Amount	Tax	Total	Notes


13	2007-10-06	Client 3	1000.00	0.00	1000.00
12	2007-10-06	Client 2	700.00	140.00	840.00
11	2007-10-06	Client 1	600.00	120.00	720.00
10	2007-10-06	Client 2	100.00	20.00	120.00
9	2007-10-06	Client 1	200.00	40.00	240.00
8	2007-10-06	Client 3	200.00	0.00	200.00
7	2007-10-05	Client 2	120.00	12.00	134.00
6	2007-10-05	Client 1	50.00	10.00	60.00
5	2007-10-05	Client 3	100.00	0.00	100.00	no tax at all
4	2007-10-04	Client 3	150.00	0.00	150.00	no tax
