My requirement is to add a background color of selected items in a table

Questions
1

Though I was able to getSelectedItems. Is there a way to get items that were deselected in Skuid so I can remove color.

Harsha,
A couple of questions:
What is the use case you are trying to fulfil? (How does it differ from the theme builder capabilities) 

Also, could you show the source code for your attempt?
