This sample uses the Extend method of the Nested Table to add members within a FOR loop.
An IF statement is used to assign the values according to the value of the integer i as the FOR loop is executed.

This code iterates through a FOR Loop 3 times to show that the Nested Table has been initialized with 3 Null members.
The values of the Nested table are then assigned and another FOR Loop iterates 3 times to output the values of the Nested Table once again. 3 lines with no results from the null values and 3 lines with the populated data.
