Use Formulas in Table Cells
Table cells can contain formulas that do calculations using the values in other
table cells.
With a table cell selected, you can insert formulas from the Table Cell visor.
You can also open the In-Place Text Editor and enter a formula in a table cell
manually.
Insert a Formula
In formulas, cells are referred to by their column letter and row number. For
example, the cell at top left in the table is A1. Merged cells use the number
of what would be the top-left cell. A range of cells is defined by the first and
last cells, with a colon between them. For example, the range A5:C10 includes
cells in rows 5 through 10 in columns A, B, and C.
A formula must start with an equal sign (=). The formulas for sum, average,
and count ignore empty cells and cells that do not resolve to a numeric value.
Other formulas display an error (#) if any cell in the arithmetic expression is
empty or contains nonnumeric data.
Use the Cell option to select a cell in another table in the same drawing. When
you have selected the cell, the In-Place Text Editor opens so you can enter the
rest of the formula.
Copy a Formula
When you copy a formula to another cell in the table, the range changes to
reflect the new location. For example, if the formula in A10 sums A1 through
A9, when you copy it to B10, the range of cells changes so that it sums B1
through B9.
If you don't want a cell address to change when you copy and paste the
formula, add a dollar sign ($) to the column or row part of the address. For
example, if you enter $A10, the column stays the same and the row changes.
If you enter $A$10, both column and row stay the same.
Insert Data Automatically
You can automatically increment data in adjacent cells within a table by using
the AutoFill grip. For example, a table with a date column can have the dates
