@evan just shared a great tip with me. I had a column with a series of items in it, and I realized that I should have made it a lookup column. I was dreading starting over, but good news! You can create a lookup column from a table that doesn’t exist yet:
You can choose to create a new table from your column results. Coda will create a new section with the new table inside it.
Ended up being super handy and saving a ton of time!
