Dear @Per_Bonomi,
In the past my reaction was similar, but I learned in this community something important.
Create you table base and use as many columns as needed. (if you make really big and complex structures, you could add symbols in the naming of columns to easy identify the support columns for example)

In the areas where the users will interact, you only use views that are both filtered and have the non relevant columns hidden. Think also about what view of your table would suite the most, to my opinion the “details view” is underestimated on it’s potential
With the support of buttons, you can make it even more user friendly
The example of @Paul_Danyliuk is a good sample how to use buttons to navigate:
