Description of the illustration dwhsg084.eps
This figure illustrates the example of an In table containing:
- 
                  North 10 
- 
                  South 20 
- 
                  North 25 
- 
                  East 5 
These are in columns of Region and Sales. They then go into a table function, which leads to output of:
- 
                  North 35 
- 
                  South 30 
- 
                  West 10 
- 
                  East 5 
This is a simple example, and is not meant to illustrate syntax.
