I have a printed invoice where the first two line item fields are "part number" and "description", and often the description field is used for descriptive text that can be a whole paragraph. In this case, the part number field isn't used. I want to make the description field expand to use the whole space to limit it's vertical space. I set this field to both auto-size it's width and slide left, resulting in it sliding left but staying the same width. Does sliding trump auto-sizing? What is the relationship between these options?
