I am pretty new to YUI and need some help.

I have a JSON response like this:



I would like to have a datatable with nested columns where:
1) alpha, beta and gamma are parent columns.
2) beta and gamma each have two columns formed of the JSON key-value pair (e.g., delta => 2.975).
3) The number of rows, i.e., total key-value pairs, is dynamic.

Basically, something like this:



I have been able to generate non-nested, simple JSON responses.

My problems:
1) I have the object for each JSON child ({theta:0.339}, etc.). Both child columns will need data from this same object. How do I use it without modifying it? Should I use the same 'keyName' for both child columns in myColumnDefs?
2) How to create more than one rows where alpha td is empty?

Any help will be appreciated !

Thanks, Satyam ! I figured it would be easier for me to use a supported format. I flattened my data into rows of fixed width (columns) and inserted keys for each field. That solved my problem. Thanks for your time !
