eclipse-rcp - How to edit a table row on same window in Eclipse RCP ?

Question

I have a table with many rows on a window. I want to edit a row. I have two options

1. I can open that row values in editor and then save.
2. I can open that row in the same window (beneath table), edit and save (same like above but on the same window where I am showing table).

I want to do second option.

any help (more details can be provided if required to understand the question)
