The way a list appears is determined by the view format: For example, which fields appear and in what order, how the list is sorted, the typeface used and so on. View formats can be set public and thus available to all colleagues, or set to private and only be available to you.
For every data record type, there is a Default view format. These view formats will then be used in all clients if you have not set a special view format for a list. The Default view format (public) can only be created and edited by your administrator.
Users can edit their own and public view formats as well as default view formats if they have been given the rights to do so by their administrator.
