I tried to view samples:
http://docs.webix.com/samples/15_datatable/30_treetable/05_filter_custom.html
http://docs.webix.com/samples/15_datatable/30_treetable/04_filter.html

Data is not loading. I see in console following error:
Failed to load resource: the server responded with a status of 500 (Internal Server Error) :http://docs.webix.com/samples/15_datatable/30_treetable/data/treedata.php

Please advise.

Sorry for inconvenience.
It was a problem with local Database. All samples must work correctly now.
