Click the title of the column you want to sort by, whether Name, Status, Asset ID, Author Username or whatever. As far as I know there is no way to do a nested sort, like Author then Type or anything like that. When you click the title of the field, it will sort to the smallest value first, so if you are looking for Build Version or Upload Date, you will want to click twice, to get the highest build or most recent uploads at the top. Status works great for getting unknown dependencies to the top for routes and assets.
