Based on the documentation, yes - the table settings dropdown is where you can view and edit table descriptions. You access this by opening your table settings dropdown and selecting "Edit table description." [1]
For tables, find the dropdown in the left section of the top navigation bar. For workbooks, it's in the bottom workbook navigation bar. [2]
If you need any more help with viewing or editing table descriptions, please let me know. Would you like to share more about what you're trying to achieve with your table?
