If you want to see your chapters row-by-row, I think the best way to do this is creating a separate table with client-chapter links one-by-one and group this table by clients.
However, if you want to select chapters in one place and then just fill some table, here is an automatic way to do this (see Links list and Auto table):
You select your chapters in links list and they automation rule fills auto table. You can add to auto table any columns from client and chapter you want.
Note, this solution is pretty slow and overengineered because of CurrentValue scope problem. I am really looking forward when Coda’s developers will fix that.
