Can I reorder columns in a pivot table?

I have a pivot table block with year as the column. But by some logic I can’t detect, the years are not sorted numerically. And I can’t find a way to arbitrarily reorder the columns in the pivot table to put 2018 in its place. In my Year table, the years are in numerical order.

What am I missing?
