Grouping TableTools buttons

Stpdude

Hey guys, so i have my row of table tool buttons including a couple custom ones. Id like to be able to space them apart by type, so like have the add/update/delete buttons together, then a bit of spacing, then the select/deselect, then more spaces, then the print/save buttons together. I havent figured out a way to do this yet. Anyone have any ideas?

Thanks!
