Table visual re-sized when pinning to dashboard

I have a report with a table visual that include a "color" column which I have shrunk down to only show the background color:

However, when this report gets pinned to a dashboard, all of the columns are resized, which reveals the number behind the color (and the column title, which I really don't want to see).

Is there a setting I am missing or is this just an issue with table visuals on a dashboard?

Thanks,

David Edelman
