Ability to specify any io.input for table filtering

[albertorestifo]

It would be very useful to be able to show some custom filtering fields on top of a table.

Having a simple text input doesn't cut it for all use-cases, and given that there is already the ability to dynamically fetch data for a table, it would be really awesome to be able to specify some custom inputs.

For example, if we have a table listing all users, I might want to display an email input field in the table header, so Interval users can then easily filter the table by email.
