I have recently created a new GitHub repository for my code seperation of Alex Harui’s combination of Spark List components to build a datagrid. As my notes say:

I have basically taken Alex Harui’s example from
http://blogs.adobe.com/aharui/2009/12/spark_list_spark_list_spark_da.html and broken it up into more bite size chunks,
added some styling and various other attributes to try and make it more flexible? Here is an example application using
the source http://demo.newtriks.com/ExampleSparkDataGrid/

SparkDataGrid

This is by no means perfect but I did manage to get some sort of separation to be able to use in a couple of projects quite nicely and as a simple grid it works fine, have a play and fork the project to offer some improvements.
