Is there a way to assign a unique identifier to a column? The columns contained in my grid can be dynamically selected by the user, and I need a way to indentify each column.
The column index is a unique identifier (it is not the same as display position). You can also use string indices instead of numbers if you wish -

Or, you can add new properties to the column or cell models with
defineColumnProperty or defineCellProperty.
