You can copy and paste a table into Tettra from an external source like a Google sheet or Excel doc.
Start by selecting the table you'd like to add and copying it:
Once you've done this, open a page in Tettra, right click within the body, and select 'Paste'.
To embed, you'll need to grab your "Shared Table view" link from Airtable, accessible via the "Share" button. For more Airtable guidance, check out their documentation here.
