Not sure if you really want to use both Graeme's solution and mine. His is elegant. I could see an argument being made to move the line data to the first column as a permanent fix.
Not sure what is happening with the column resizing for you, it could just be that you are not gripping the resize bar in the header in the exact right place. It will not let you "push" a column to the left, but none of these are configured to be fixed with columns.
