overwrite field and do not change the order

[liuhetongzi]

I overwrite field for a foreign key, the column name is not changed, when i export the model, the field is in the first column，I expect the field is in the origin column，I know I can use export_order ,but i have many fields, and many tables, I want to use a general method.I do not want to write column in export_order one by one.

I want dc column in second column

Thank you!!
