Right now you need an intermediate tool. See Commons:Convert tables and charts to wiki code or image files. Go to the section currently titled something like: "LibreOffice Calc to tab2wiki". It explains how to use freeware LibreOffice Calc to move columns around.

Paste your table into LibreOffice Calc, and move the columns around there. Then copy it from there and paste it into tab2wiki. Copy the table wikitext from there.
