Any difference between hiding a column applicatively and giving it a zero width?

[targumon]

I have a table where one of the columns should or should not be visible.
I'm aware of toggleHideColumn().

It happens to be a case where I set a width for that column (i.e. instead of letting the browser do its thing).
Which made me think - I can alternatively hide the column (visually) by setting the width to 0.
The upside is that I can also set something like transition: width 0.2s to make the toggling effect more pleasing (toggleHideColumn is certainly not 😕).

Beside extra a11y work (I'll have to hide the column from AT as well), are there other downsides to this approach?
