Structured references allow you to easily work with cell references and formulas in a table. For example, instead of using a cell range reference such as F2:F52 in a formula, you can refer to the cell range as Sales (the table column name). They make it easy to see, at a glance, what the formula is calculating.
When you create a formula using structured references, you can use several different elements in place of the regular arguments. These include the table name, column header names, or special items that refer to areas of the table, such as a total row.
