Chapter 10: Introducing Formulas and Functions


217


Although the formula was entered into the first row of the table, that’s not necessary. Any time a
formula is entered into an empty table column, it will automatically fill all the cells in that column.
And if you need to edit the formula, Excel will automatically copy the edited formula to the other
cells in the column.

Note
The “at” (@) symbol that precedes the column header represents “this row.” n

These steps use the pointing technique to create the formula. Alternatively, you could have entered
the formula manually using standard cell references rather than column headers. For example, you
could have entered the following formula in cell E3:

=D3-C3

If you type the cell references, Excel will still copy the formula to the other cells automatically.

One thing should be clear, however, about formulas that use the column headers instead of cell
references: They are much easier to understand.

Tip
When you add a formula to a column in a table, Excel displays a SmartTag. To override the automatic column
formulas, click the SmartTag and choose Stop Automatically Creating Calculated Columns. Use this option if
you need different formulas for different rows within the table. n

Referencing data in a table .......................................................................................


Excel offers some other ways to refer to data that’s contained in a table by using the table name and
column headers.

Note
Remember that you don’t need to create names for tables and columns. The table itself has a range name,
which is provided when you create the table (for example, Table1), and you can refer to data within the table
by using the column headers — which are not range names. n


You can, of course, use standard cell references to refer to data in a table, but using the table name
and column headers has a distinct advantage: The names adjust automatically if the table size
changes by adding or deleting rows. In addition, formulas the use table names and column headers
will adjust automatically if you change the name of the table or give a new name to a column.

Refer to the table (Table1) shown in Figure 10.11. To calculate the sum of all the data in the
table, use this formula:

=SUM(Table1)
