Help with Lists

[David Burgun]

Hi,

I need to make a window that has a list of items arranged in colunms as:


ColA    ColB     ColC     ColD   ColE

I need to be able to have the user click on any of the "Cols" and 
have the list sorted by that field. Also I need to be able to Option 
Drag the colunms so as to rearrange them, as in:\\

ColB     ColC   ColA     ColD   ColE

If the user Dragged "ColA" onto "ColC".

How do I go about doing this? Is there a sample I can get started 
with? Any pointers would be greatly appreciated.

All the Best
Dave
