I use Ultraedit and there you can switch easily to column mode. Column menu or Alt + C. When you then start your selection by mouse you can select fe. from columne 10 to 15 from line 1 to 20. And then cut and paste.
But sure there are a lot of editors that can switch into column mode. Did not find it in notepad++ however, where is it hidden ?
