For some reason XVI32 defaults to 17 columns wide; you can change that in the options to the standard 16, or you would be off when following my instructions whenever you need to count up or down a certain number of rows.

For the first column, that is basically just row numbers, which you do not need to use at all (the relative position of what you want to edit changes as quest or NPC data is changed, etc, so you never know that something in particular is always going to be on a certain row).
Hackman and XVI32 use different notations for the line numbers, so they are not going to look the same.

For any particular search term, it can show up anywhere in a row or even started on one row and continued on the next. Only the relative position matters.
