Retain Column Width on Table & Matrix

When you switch off auto-column width sizing as property setting on either visual, you actually want to control the width manually or via the Measure-hack-trick. But sometimes measures change and you add/remove fields in the visual. It would be great to retain your custom width settings and not reset it when making changes to the fields - especially when auto-column width sizing is turned OFF. It takes a lot of effort to display these columns perfectly, and having to redo this takes a lot of effort and wasted time.
