Reorder Report Columns
welcome to the community!

First up, I would not recommend learning to code by editing CiviCRM Reports.

The thing to exhaust before reaching for your Dial-a-Coder is the CiviCRM Profile option for an Advanced Search. You can get the information that you need from Civi 99% of the time using cleverly created Profiles, and then using them as a "Search View" on an Advanced Search.

If (and Only If!) you've exhausted that, then it may be best to ask a CiviCRM Partner organisation to help you. They can be found here: https://civicrm.org/partners-contributors.

Good luck!
