title: checkboxes in ng2-smart-table
body: <p>I am using ng2-smart-table in my project, I want to add a column with checkboxes which while rendering will be checked based on the object which binds the table.
  In the object, there is a field with a boolean value which will determine if the checkbox will be checked or not, and after making changes in the checkboxes, the changed values should be available. </p>
