Sometimes you can't change the Colum ordering of a list or library
Sometimes the link (in the list or library settings) about the Colum ordering is not visible. If you want to change the column ordering of the SharePoint 2007 Form in that situation you can edit the url e.g. from:
http://my-url/_layouts/listedit.aspx?List=%7B02B1A398%2D7077%2D47AF%2DA455%2D4C4E82C77CC3%7D
to
http://my-url/_layouts/formEdt.aspx?List=%7B02B1A398%2D7077%2D47AF%2DA455%2D4C4E82C77CC3%7D
As you can see you only have to change to part before .apsx from listedit to formEdt.
