My client wants the underlying data in a particular order

I have tried renaming the fields in alphabetical order it did not work.

I have tried renaming the fields in numeric order it did not work.

I have tried renaming the fields in a combination of alphabetic and numeric order it did not work.

I have tried to put all the fields in a calculated field and order them by renaming it as C001_,C0002_

but it also did not worked.
