The tables area on the left shows each of your individual tables. If you have a Google Sheet as a source, you'll see each of its individual sheets here. If you're using Glide Tables, you'll see these as well.
The sources area on the bottom left is where you see your data sources. This will grow in the future as we add the option to add more data sources. For now – this just shows the Google Sheet that you can refresh or click on to visit.
The main area is the actual data grid itself. Here you can scroll, interact and edit the data you see.
The data editor has its own top bar – which shows the Preview As dropdown, the name of the current table, the Find Column search box, and the Add Column button. Learn more about the Data Editor below 👇
