In this case, wrappering your table.console() call(s) with console.group()/console.groupEnd() doesn't seem like such a huge burden to me.

Yes both uses cases are correct.

The original point was related to the other console methods that mostly takes a string/label as the first parameter, but looking at the list again we can see that console.dir() and console.dirxml() also doesn't expect a label and so, the developer needs to use them together with console.group() in order to make them expandable. It looks like the console.table() could also fall to this category.

So following needs to be written if the label parameter is avoided:
console.group("My Table")
console.table(object, [columns and headers definition]);
console.groupEnd();

So, thinking about this again, it's ok for me if the parameter is not there, it'll be probably easier.
