I've setup both at this point,
If you have both Subscriptions on the User Account on this Tenant at same time i.e. Both the M365 / O365 Developer and the Power Apps Community Plan, you will no longer be able to test how it is like with just M365 / O365 Dev subscription by the way. So the only way to test it is to have only the M365 / O365 Dev subscription on the tenant. To do this you may have to create one or more Users and only assign the M365 /O365 Dev and not start the Power Apps Community Plan from that individual user.
Now the Default environment you can create a Table there, but the question is in M365 O365 dev can you make a Canvas App and use Table as data source? The answer is I would say not technically - now even if you were able to do that for some reason anyway, once you shared that with another user with O365 / M365 dev they should be prompted to start a trial of Power Apps Per User because it uses Premium Features.
Now it's possible for some reason what I am saying is wrong and that it's just going to let you do all of this anyway even share it with the other user, even without PA Community Plan. If so, it might just be some special exception for the M365 / O365 Developer plan or something.
