Frozen columns and other grid features

In this document about column manipulation for the grid component

[ ... pulation&s]([]=This&s[]=mode&s[]=is&s[]=incompatible&s[]=with&s[]=some&s[]=grid&s[]=functionality#split_mode._frozen_columns

there is this sentence about using the frozen column feature.

“Note: this method should be called when the grid is initialized. This mode is incompatible with some grid functionality.”

What grid functionality is incompatible with the frozen column feature?

Also, is this the same for both version 2.6 and 3.0?


Forget “splitAt()” or you get a lot of mystical effects in different browsers (IE8, Safari).
