title: adding rows inside grid extjs
body: <p>I am trying to add rows dynamically inside a grid using a button and remove individual rows using an action column function.  I have two text fields (name, email) inside the grid on each row. So when the user hits the add button, a new row should appear with name and email fields. The third column would be an action column and when the button in the action column is clicked the entire row should be removed.</p>
  
  <p>It would greatly help me out if somebody could share some sample code for me to get started.</p>
