Handle main and secondary Table global actions

[luciob]

In table component provide a way to differentiate between main and secondary global actions.
main actions are rendered with a Button, while secondary actions are rendered with an IconButton.

A good way to do this without asking the user to provide specific detail is silently picking the first global action as main, unless differently inputed by the user.
