Automatically adds computed columns
HI k-k-k-k
A table can add calculate column by the self after the dataset is loaded and a DAX formula is specified for it so that it knows what to add as a values in the column. It will happen for every refresh but external data like config file cannot trigger it.
Thank you very much!
Just think about, whether M language can do it? For PBI table structure extend can not be auto-complete by configurate external parameter? thanks!

"table can add calculate column by the self.It should be happen after refresh and the external data like config file will trigger it"
Can you defile self? Either DAX or M need to come into play only after the daatset is loaded.
Which config file? I am not aware of any config file on Power BI.
There is no way "external data like config file" will trigger it.
Anonymous Thanks, actualy the external config means data from files or other source. it's just data. the action is drived by specific data's change when refresh. for example: when a number in source table changed from 1 to 2 , and after refreshed, the table in PBI will automantic add column . looks it is impossible.
