Using Formulas and Functions in Tables

To apply a header formula to cells in a column or row:

1

Select the header cell for the column or row.

2

Open the Formula Editor. For example, type the equal sign (=).

3

Type the formula you want to apply to each cell in the column or row.

For example, to assign values to the cells of column C that are five times greater than
the corresponding cell in column B, you’d use the formula B*5 or B:B*5.

The formula is duplicated in all the cells in the column or row. In this example, cell C4
would contain the value computed by using the formula B4*5.

4

Click the Accept button or press Return or Enter to save the formula.

Handling Errors and Warnings

When a formula in a table cell is incomplete, contains invalid cell references, or is
otherwise incorrect, or when an import operation creates an error condition in a cell,
Keynote displays an icon in the cell. A blue square in the upper left of a cell indicates
one or more warnings. A red triangle in the middle of a cell means that a formula error
occurred.

To view error and warning messages:

m

Click the icon.

A message window summarizes each error and warning condition associated with the
cell.

Using Operators

Use operators in formulas to perform arithmetic operations and compare values:
 Arithmetic operators perform arithmetic operations, such as addition and subtraction,

and return numerical results.

 Comparison operators compare two values and return TRUE or FALSE.

Performing Arithmetic Operations

To create a formula that performs an arithmetic operation, you use arithmetic
operators. For example, to add three values in a column, you could create a formula
that looks like this: A2 + A3 + A5.
