What is a lookup column?

A lookup column (or field) is a field in a table whose value is retrieved from another table or from a value list. You can use a lookup column to display a list of choices in a combo box or list box. The choices can come from a table or query, or they can be values that you supply. You can create a lookup column manually by setting a field's Lookup field properties, or automatically by completing the Lookup Wizard. Whenever possible, you should use the Lookup Wizard to create a lookup column. The Lookup Wizard simplifies the process and automatically populates the appropriate field properties and creates the appropriate table relationships.

Create a lookup column in Datasheet View:

By default, when you open a table, it opens in Datasheet view. You can add a lookup column by clicking Lookup Column in the Fields & Columns group on the Datasheet tab. doing so starts the Lookup Wizard, which leads you through the process of creating the lookup column.

  • In the Navigation Pane, double-click the table in which you want to create the lookup column — this opens the table in Datasheet view.
  • On the Datasheet tab, in the Fields & Columns group.
