What if you want to increment the value of one of the columns of your fixture table at run time? You can use the IncrementColumnsValue decorator. This lets you increment column's values. This decorator supports the following data types:

• int or integer
• double
• string
• date

Increment Columns Value	numerator	of type	int	by	5
Division
numerator	denominator	quotient()
10	2	5
10	3	5
10	4	5

Increment Columns Value	numerator	of type	integer	by	5
Division
numerator	denominator	quotient()
10	2	5
10	3	5
10	4	5

Increment Columns Value	numerator	of type	double	by	10.2
Division
numerator	denominator	quotient()
10.2	2	5.1
10.2	4	5.1

Increment Columns Value	numerator	of type	string	by	5

This decorator by itself is not as useful. But piped with other decorators this can be really handy.
