About columns

Columns display the information that constitutes each item in a list or library. At the top of each column is the name of the column.

When you add an item to the list or library, you fill out a form in which each column is represented by a field. Each field is labeled with the name of the column. If you provide a description for the column, the description appears below the field. You can use the description to help team members fill out the form by explaining what kind of information goes in the field.
