Unless you specifiy otherwise through expand and weight options, grid 
columns are the minimum width required for the widest minimum width of 
any widget in the column.

The columnspan makes the minimum width of 'description' the minimum 
width of column 1 plus the minimum width of column 2.  With nothing else 
in columns 1 and 2, it has no effect.

Try reading the grid page at
http://infohost.nmt.edu/tcc/help/pubs/tkinter/web/index.html
if you can get it to load.  (I did a couple of days ago, but not today.)
