You might want to try this:

Load the Table (T) and Chairs (C) and position them where you want for a default configuration.
Note -
You might want to parent the C's to the T before you save the (compound) prop in the Library.

Now ...

1. Save the T in the Props Library and use the "Select Subset" button
2. Select the T and as many C's as you want to include in this compound prop.
3. Save the "T+C" in the Library

Using the "T+C" prop

When you load the "T+C" prop you will get the table and chairs in their default positions.

The chairs are still separate props and can be moved independent of the table but ...
You can, also, move the group (if you parented the chairs) just by moving the table.

Need a bunch of table and chairs?

Set up your groups and then save (using the Select Subset button) ...
... all the groups in the Library as a single (compound) prop.

Make your group(s) as big as you want.
