How do I change the position of a column in a table

I put the primary key to the far right of a table in design view (bottom row), but want to move it to make it the first column on the left (top row in design view). I thought I could simply drag and drop or just insert a row at the top of design view and copy and paste the row, but I can’t do this. How can I?

Thank you.
