Hi Gargoyle,
Tables in Pages are similar to Tables in Numbers. Here is an example with a Header Row (Row 1), a Footer Row (Row 5) and a Header Column (Column A):
Formula in Cell D2
=Cost each ChairĂ—Number ordered Chair
Pages by default uses the labels in Header Rows and Header Columns as Cell references. Numbers (usually) uses the Column (A, B, C, D) label and Row 1, 2, 3, 4, 5) label as Cell references.
To Fill the formula down from D2 to D4, drag the yellow dot (Fill Handle) down.
To add another row containg the formula, click in a cell in Row 4 and press option down arrow.
Fill in the details in Columns A, B and C
The formula in D5 calculates the cost for that Row.
Formula in Footer Cell D6
=SUM(Cost)
