New Post: Change IEEE Reference column width

Look in the source for

<td align="{$params/bibliography/source[@type = $type]/column[@id = $columnId]/halign}" valign="{$params/bibliography/source[@type = $type]/column[@id = $columnId]/valign}">

If you can update the td to use a fixed (or percentual) width in case of column id = 1, you might be able to get what you want.

Note that I have not tested this at all.
