But it really doesn't. People will try to do simple calculations as they are used to do in Excel and they will quickly find out they can't do much beyond a simple pivot. Everybody I have see using Tableau is using calculations and a lot of them even LOD calculations. Do this exercise, check what business people really do with Metabase and Resash, I have a feeling they use them to download data into Excel... I totally agree we need something cheap and simple, but it must have some level of "functional" calculations a la excel. Now if users were exposed a pandas dataframe in Superset or Redash or other, that would be extremely cool and would for some cases be much better than Tableau.
