Column Aggregate functions in version 2.2

[PENDRAGON]

I've scoured the forums and docs for the 'sum' aggregate function that was available in version 1.7.  I saw the post that said it was missing from version 2.0 but would be back in future versions.   Is it present in 2.2 in a way that functions like the version 1.7 example ( http://www.sigmawidgets.com/products/sigma_grid/demos/example_aggregate.html ).

I load data in dynamically (PHP) and use var gridOption and var colsOption to define variables so I'm not sure if I add a "var context" as in the 1.7 example where I call it. I assume I put it as a key : value pair under gridOption but not sure.

My colsOption variable defines columns with an "id:" tag and not a "name:" tag as referenced in the 1.7 Aggregate example.  I assume I could just add a "name:" identifier for each column that I wanted to reference for aggregation.

Here's how I call the grid now:
var mygrid=new Sigma.Grid( gridOption );

Any help to get to the exact functionality of the 1.7 demo above would be great.

I am sorry for this response so late.
I tried your grid and its look nice.
Today I just figure out how to make my subtotals.

Perhaps a lot of people want the aggregate function in grid.
I found a way that i can make a lot of subtotals and i can show them in the bottom of grid or in the top o the grid.
Basicaly I create 2 arrays from my database.
First is with actualy data that I need to show in grid and seccond with my subtotals.

The arrays must be the same in order to concatenate them.

<?php $retArray=array_merge($retArray1,$retArray2); $data = json_encode($retArray); ?>

An example is in picture below.
