A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
Hi Peter,
Welcome to Microsoft Community. I understand that you want to know about using formulas in OneNote table.
You can create and edit tables directly in OneNote but it is not possible to use aggregate functions (e.g., sum, average) on OneNote table columns.
If you want to capture, share, and analyze a list of structured information, inserting Excel workbooks into OneNote pages is a useful option.
Please refer article: Add an Excel spreadsheet to a page in OneNote 2016 for Windows
Hope this helps. Please reply if you need further assistance.
Thank you.
