How to add more than 3 columns in editable grid?

@ramyad You could add the column (intended for providing comments) in the paging grid. Initially this column might be blank as it won't have any values until and unless we add some text. Once when you select a particular row, submit the form and navigate to a new user input task where you can update the contents of the chosen row (that is, provide an editable text or paragraph field in which you can provide some comments and update the same in the column of the CDT variable which is chosen for the update). Once when you are done with the update of the chosen row, navigate back to the interface which will actually surface the grid and provide an ability to select row and update it.

I know that the whole process specified above is cumbersome, but until and unless you go for an upgrade in the version, you wouldn't be able to leverage the Appian's features.
