Allow fixed column widths in List View
It is often times necessary to control the column widths in a List View. Currently, the columns are based on a percentage. Examples when having a fixed column is useful, is when you have a column that has a max size for the data inside of it. You don't want it to take up any more screen real estate than it needs to. It is pretty standard in any list view control (Windows, Web, etc) to have ability to specify fixed column widths for certain columns, and allow other columns to grow/shrink.
