I attended a class yesterday for some hands on Power BI training. Out of the 14 attendees I was the only one having this issue.
Steps to reproduce:
1. Create a new Power BI report.
2. Select Modeling / New Table, and enter the following DAX:
3. Table = DATATABLE("a", integer, "b", integer, {{1,2}})
An error message appears: The tuple at index '1' from the table definition of the DATATABLE function does not have the expected number of columns.
I am running Power BI Desktop version: 2.78.5740.861 64-bit (februari 2020) on Windows 10 Pro, version 1909.
I did play around a bit with the regional settings before these problems started. I have tried removing and re-installing Power BI Desktop, but this error keeps coming back. I have also installed the Dutch language version, in wich the data separator character is ; but the problem remains. Any help much appreciated.
