Value mappings not working in table

  • What Grafana version and what operating system are you using?
    8.3.6 in Docker

  • What are you trying to achieve?
    I want to have table cells coloured by a value mapping

  • How are you trying to achieve it?
    I try to use the Overwrite Value mapping

  • What happened?
    The cell colour does not change

  • What did you expect to happen?
    That the cell colour is changing according to the value mapping

  • Can you copy/paste the configuration(s) that you are having problems with?
    Table + overwite:


    Overwrite config:

  • Did you receive any errors in the Grafana UI or in related logs? If so, please tell us exactly what they were.
    No

  • Did you follow any online instructions? If so, what is the URL?
    /docs/grafana/next/panels/format-data/

You need to set also cell coloring mode (e. g. bacground) in the panel config.
