Description of problem:
I've made this datatable responsive with debounce, and the layout changes depending on the screen size.
My issue is, all the buttons disappear on certain settings after a resize.

Currently, when the datatables is initialized on either desktop or mobile screen size, the buttons display correctly at first.
But when I resize from either to the other size, the buttons disappear. And I get the error message shown above.

Furthermore, I notice when I remove:
visible: false

from:
columns: [
{ title: "Name", visible: false }, ]

this issue doesn't occur.

Also if I remove:
ordering: false,

the issue doesnt also doesn't occur, even if I still have the "visible: false" from before.

I don't have an immediate answer I'm afraid. I'll need to spend a bit more time than the 5 minutes that I've just poked around with this on it. I'll try to do that in the next few days.

Hi,

Fixed with this commit. I'll release 2.1.5 with this fix next week.
