Going back to psm 3, I did find that textord_tabfind_find_tables 0 helped, 
in that it draws only one box around the "block" of text, instead of the 
three that I was first getting. This is obviously the same as psm 6, but 
psm 6 should not run column detection, which is something that I want 
unless I can get tesseract to draw "blocks" vertically around the 
individual columns.
