resize columns in view

Users currently have the ability to hide or rearrange columns in a table view when running an app. It would be nice to (a) allow the designer to set the default column width when setting up the view; and (b) allow the user to resize them.

The current sizing of columns in a table view seems to be based on some mysterious combination of: width of field name/displayname; width of widest entry in field; some max width for the entire table.

I've got some forms that contain many fields, some of them quite long. It would be nice to be able to set those columns narrower so the user can view all the fields without scrolling.
