I'm a newbie to Zoho Creator, so I apologize if these are stupid questions, but I can't find answer in the forums or in google.

I've got a form with many columns.  When I sort by one column (let's call it "A"), it works, but there's no visual indication that column is the one sorted on.  When I then sort by another column (let's call it "B"), it also appears to work, but it seems to be sorting "B" *within* the already sorted "A".

I'd like to find out how to do a few things:

1) Visually show my end users which column(s) are actively sorted on

2) Provide a way to *un*sort a column (without having to reload the page)

3) Provide a way to let the end user, ideally in one step, *un*sort any / all already sorted columns and apply a sort to a different column

4) Make it clear which is the "primary" sorted column ("A" in the example above) and which is the "secondary" sorted column ("B" above)

Can anyone tell me how to do these things?

Thanks!
