Dynamic columns of datatable

Hi guys!
Is it possible to dynamically create table columns from the data obtained by AJAX?

a) you can use autoConfig property - it builds configuration based on the dataset

b) you can load config as part of json data
http://docs.webix.com/datatable__external_configuration.html

c) you can use JS api to configure grid, it allows to add|remove columns dynamically

Thx! I found an example)

Could you send the exemple here?
