hi @Filo
Welcome to Quick Sight Community! thank you for posting your inquiry.
there is demo dashboard for dynamic measure on demo central : https://democentral.learnquicksight.online/#Dashboard-TipsAndTricks-Interactivity-Dynamic-Dimensions-and-Measures. the visual demonstrated in there is bar chart but if you go into analysis from the icon on left pain, you can change it to table. you can see how the column name for measure can be changed dynamically using parameter and calc field.
hope this helps.
kind reagrds,
Wakana
