Allow regex for data source in coloumns

[MS-HACS]

Following your basic example I tried to create a table with the battery level of all devices - most of them mobiles with HA app installed.

The sensors giving the battery level are named in the form sensor.<mobile>_battery_level or sensor.battery_level_<number>.

So I would have to add each sensor manually instead of letting the table card generate it what is the generel purpose of this great extension.

So what I would like to have is the ability to define some sort of expression, e.g.

columns:
  - name: Battery Level
    data: *_battery_level,battery_level_*
...

Are you talking about using wildcards to define processed entities? Because what you wrote for the data option seems to be wrong, it is supposed to select attributes & state.
