SharePoint List Views: This helps to re-order the columns that are displayed to the user. Below screenshot is the default view provided by SharePoint when you create a new list.
If you want to modify the way the columns are displayed to the user.
Click on the List -> Modify View as shown in the below screenshot
You will be taken to the Modify View Page.
when you change the “Position from Left” column ordering as shown in the above screenshot it will affect the view.

When you change the order of these columns then it will affect the way it is displayed to the user when he clicks on add new item. Hope this will give everyone a clear picture.
