Please select the Column that you want to remove and right-click on it open the context menu. Select the Remove option from the context menu
Now, you can see that the State-Province Code column removed from the table. And you can see the same under the Applied Steps section.

As you can see, all the other columns except City removed from the Geography table.
Alternatively, you can click on the Remove Columns button under the Home Tab
Similarly, we removed the remaining unwanted columns.
