Using canFilter

[blavonne]

Hi! Does canFilter really work?
I opened this example from site and added canFilter: false to column 'Age'. There was no result. I deleted lines 361, 362 and default filter was rendered.
{ Header: 'Age', accessor: 'age', canFilter: false, },
Console.log in my project always shows 'canFilter: true' too in sprite of my table model.
I want to use both default filter and canFilter-rule. What is wrong?
(upd: the problem was solved by adding a custom field 'filterable', but I still want to know why canFilter: false does not work)
