From Matrix to Single List

Hi Guys,

I would like to ask for pointers how to solve this. I have a table is as follows:

	SMALL	MEDIUM	LARGE	x-large
design a
design b
design c
design d

Firstly, I would like to convert the products offered from matrix to single list format, that is all the various combinations in one single list: such as this.

design a - small
design a - medium
design a - large
design a - x-large
design b - small
design b - medium
and so on.

Afterwards, I would like for the value at each intersection to be copied to the corresponding entry in the single column.


How do I accomplish this?


Thank you!
Henry
