Apologise if we mislead you - the pictures of the grid
in the blog post are missing the horizontal scrollbar which can lead to the impression that the columns are hidden. Instead the columns are not hidden, but the user should scroll to them. Our point in the blog was that the columns would not be resized, instead the overflow will be handled by a horizontal scrollbar.
Also please note that you can implement custom solution in which to detect current device that is accessing the page and render different version of the grid
(with less number of columns) if this is your current requirement.
