I've read that the column (in)visibility is still under construction, but
I have to hide some columns and when I do it I get some issues. I couldn't
think out how to do this on other way. I need to be able to set some
columns invisible (and visible again), but the Grid doesn't behave
adequately. First of all, when I move through the grid with the arrows and
the selection exits the visible area, the grid doesn't scroll. And second
of all (and the badest) when the first column (index 0) is hidden and the
focused cell is in the first visible column, when the left arrow key is
pressed, I get NullPointerException from the method Grid.showColumn(). Can
you tell me some other way to hide columns and avoid these issues.
Here's an example snippet of these ussiues:

Thank you in advance and sorry for my not-very-good English.
