Consider the simple example below – a table with various columns of data. Any formulas we create would be much more readable if we assigned names to the columns of the table.
With the full table selected, choose Insert – Names – Create to open the Create Names dialog.
The Create Names dialog gives you four options for defining the table range names. In our example, we will name each column according to the top row of the table.
With our newly defined names associated with the table, we can rewrite our formulae into more meaningful expressions.
