^^^--- Says that altering a column size is in "preview". I believe this has been working for a while now. This is a ping to review page.

Ryan Kuo can you take a quick look at this and either fix and close or comment as to why we should leave the page as is?

Hi Glenn Fawcett, thanks for filing. Dikshant Adhikari confirmed that this is still meant to be in Preview. I noticed that the session var associated with this feature hadn’t been documented, so I opened a PR to address that. This issue will be closed once that PR is merged.
