All survey content is created and edited in "blocks". The default is usually to put all your questions in one block, but multiple blocks can be useful for organization or if your survey requires more advanced techniques like branch logic.
Click the green "Create a New Question" button at the bottom of a block to add more questions to a block.
You can easily move your question by hovering over the question and using the gray arrows on the left side.
On the right-hand sidebar, look for "Change Question Type" and pick the kind of survey question you want:
Under "Change Question Type", select "Matrix Table". You can create a table-style Likert scale with this option.
Click on the filler text in the table to edit it.
Question Options (in right side bar)
Use the + and - icons to pick how many questions/items you want to ask (rows)
Use the + and - icons to pick how many scale points/possible answers there are (columns)
You can leave this at 0, or add labels to the top of the table
Pick a response style: single answer, multiple answer, dropdown, etc.
Keep in mind that not all styles will make sense. For example, if you're doing a regular Likert scale, you may not want to choose "multiple answer" because someone could choose both "agree" and "disagree".
Mobile friendly - make the table adaptable for phones and tablets
Transpose Table - switches columns and rows
Position text above - merges rows into the table
