Prevent New Record Creation

Is there any way to prevent the creation of new records in a table from collaborators with edit access?

We don’t have support for such “fine-grained permissions” at this time, but it’s something that’s on our backlog to look into in the future. Your best bet at this time is to use Zapier or our API with a third-party service that only lets users, for instance, modify a given row without supporting any other functions.
