Text field containing all data from other table

Hello,

i am looking for a way to display ALL data that is within another table. I have a sub-table (from another table, not linked to the one where the dashboard is) that looks like this:

I would like to create a dashboad, that presents all the data thats within this other db, as pairs:

Drehzahl Lüfter Wert = 70

Drezahl Lüfter Min = 0

Drehzahl Lüfter Max = 100

Drehzahl Lüfter Einheit = %

My main problem is that I have different tables with different amounts of fields and also different field names. Therefore i would simply like a textfield that presents all available information in a readably way like above. 

I hope this is understandable. Thanks in Advance

Dennis
