Now SQL Dump wizard has page where you can specify by checkbox only few tables to be dumped.
This can be suitable for example working with Joomla web site, when single mySQL database contains 200+ tables from different tools such as Joomla, Store, Mantis, WP, … So there are independent groups of tables.
WARNING: You should understand that if you dump some table A, but forget to dump linked by FK table B, you can get troubles. But most DB tools have this feature, so developers should be aware about this risk.
