From ce802ffdfc81a90a5a892a0c679c5edda4882bb4 Mon Sep 17 00:00:00 2001 From: Dirk Hohndel Date: Sat, 16 Feb 2013 17:35:01 -0800 Subject: [PATCH] Redo the print table layout This appears to make the table layout much easier to follow, much easier to modify and it has the edit benefit of working in my limited testing.
