attachHeader after init issue

(Translated by Google)

Hello

If I use .attachHeader(…) after .init(), I am forced to use .setSizes() to see the new Header.

Is this correct?

I do not see it in the documentation

Thank you

Yes, it is expected.
The grid doesn’t resize self after attachHeader command automatically, to prevent unnecessary calls during the normal way of initialization ( when attachHeader is used before the .init() call )
