Current behavior

• the TreeTable can possibly have infinite levels with children (thanks to lazy loading, which is very good!)
• expanding the TreeTable, at some point (depending on screen size) the child nodes cannot be accessed anymore

Expected behavior

• at least the hierarchy node should be resizable

Minimal reproduction of the problem with instructions

• go to http://www.primefaces.org/primeng/#/treetable
• at the demo/example for lazy loading expand a lot of levels, at some point (depending on screen size) the child nodes cannot be accessed anymore

What is the motivation / use case for changing the behavior?

• on the demo page you only have 3 columns, so you can expand a lot of nodes before the issues occurs
• if you have around 10 columns, child nodes cannot be accessed after expanding only a few nodes
• in my case i have up to ~20 hierarchy levels in reality

Please tell us about your environment:

Thanks a lot for providing this great library!
