# How to reference a cell of a Word table

In the formula you can use a cell address to refer to a cell. A cell address format for the Word table is the same as in Excel:

- Columns are named as
**A**,**B**,**C**, etc. - Rows are named as
**1**,**2**,**3**, etc.:

See How to add, subtract, multiply and divide cells in a Word table for more details.

So, when you create a formula, you can use a cell address as a name of column plus name of its row. For example:

- a cell in the first column and the second row has an address
,*A2* - a cell in the third column and the third row has an address
.*C3*

*Attention!*

- Be very careful, if you have merged cells:
- The merged cells of one row change the column numbers for other cells.
- The merged cells of one column don’t change the row number for other cells:

For example:

In this example, there are two different tables to show formulas of calculating sum of entire column, the value of cell

is zero (0) because this cell is missed.*B4***We strongly recommend avoiding merged cells!** - Be very careful with values in the table. All formulas and functions work only with numbers.
So, you can’t use in cells that used in formulas any character except:
- Digits (0-9),
- Decimal symbol (can be a decimal point or a comma),
- Digit grouping symbol (can be a comma or a decimal point),
- Negative number symbol (usually -).

You can’t use the currency symbols or separate numbers by spaces, etc.

See How to see or change decimal symbol and digit grouping symbol in Windows 10.
