This article covers the Legacy editor. Lessons built in the New editor work differently. To add a table in the New editor, see Adding images, tables and code to a lesson. New to the difference between the two? Start with The new lesson experience.
Adding a table
Open the lesson from My Library. The Legacy editor shows the lesson as a list of blocks, with the Outline down the left.
Click into the block, then use the table button in the formatting toolbar. Type into the cells as you would anywhere else.
Click Save when you are done.
