A view makes it possible for you to change the way a list is presented according to your imagination. As such you may modify the order of appearance of list rows, set automatic filters or exclude certain cells from the list. To define a new view navigate to the SharePoint-Toolbar and select the tool Create view via the tab LIBRARY or LIST.

You are redirected to a new site, which allows you to select the type of view you would like to use for your data.

Here you get to choose between...

Standard View
