Thank you Mark. The macro is a nice thing, but it is not a filter. This 
allow to build the html for a sorted table.

But there might be some case where I would need to refine the filter to get 
a whole list of more complex data out of my filter. BUT this is not true as 
of now.

With your help, I can achieve what I want in a reasonable amount of code, 
and clear code. That's great!
