It isn't possible. Nor is it really necessary, since you can ask for
columns in any order in a SELECT.

If you really want to do it, you need to dump the table to a new table
with the columns in the desired order; delete the old table and rename
the new one.

Alternatively, add the new column (which will come at the end), add a
new address column and set its contents to be the same as the current
address column, finally drop the old address column. (This will waste
space in the table.)
