ExtJs components in GridPanel columns

My first blog of the new year.. Wishing all my readers a very Happy and Prosperous New Year 2011....

Coming to the topic, I have needed to have ExtJs components in GridPanel columns many times. I have been using ExtJs components in GridPanels for sometime now, but thought of writing a blog post for it only after I saw a couple of people having trouble doing so.
