Dear CeliaL,
1. Next Page Flow Table Format is not available in Adobe Analytics 'Workspace', but it is available in 'Reports & Analytics'.
But the Table Format is only 'one down'. I still use 'Reports & Analytics' for a few reporting requests.
2. Again, compare time periods directly in the calendar function is also available only in 'Reports & Analytics'.
Not sure whether you already knew it and asking the question for 'Workspace', anyhow said. If you are expecting it in 'WorkSpace', the options are not available right now.
Thank You, Arun.
