User Selected View Table Fields... How To??

[eluser]dhall[/eluser]
I have a single database table with roughly 20 fields.
I want to give the user the ability to select which fields they view in a table on my site.

Here are my thoughts on how to do this.
Give the user a list of all fields with a checkbox for each.
This is then saved to a different database table.
When the user calls this particular page it first pulls their selected fields, puts the results into a mysql query somehow, then builds the table with the results.

Does this sound correct?
Anyone have a good example of this or some helpful advice?

Thanks!
