-The feature enables the ability to set options on a per column basis.  This allows you to do things like explicitly
-specify which column should be sortable, editable, etc.  For example, if you wanted to prevent editing on all columns
-except for a column named `'A'`, you could do the following::

-This feature allows a user to specify whether or not a particular row should be editable. For example, to make it so
-only rows in the grid where the `'status'` column is set to `'active'` are editable, you might use the following code::

+**Events API**:
 The Events API provides ``on`` and ``off`` methods which can be used to attach/detach event handlers. They're available
 on both the ``modin_spreadsheet`` module (see `qgrid.on <https://qgrid.readthedocs.io/en/latest/#qgrid.on>`_), and on
 individual SpreadsheetWidget instances (see `qgrid.QgridWidget.on <https://qgrid.readthedocs.io/en/latest/#qgrid.QgridWidget.on>`_).
