It is possible to delete an entire table. The 'trick' is selecting the table first.
Important Note: When you delete a table, you also delete all content in that table.
1. Click anywhere on the table.
2. Click on one of the corner boxes to select the entire table.
3. Click on the down-facing triangle next to the table button.
4. Select Delete Table from the dropdown menu.
5. Click either Publish or Update to save your work.
