As PM 2Ring already suspected in the comments, you are using a proportional font. Simply importing pango and adding self.textview.modify_font(pango.FontDescription('monospace')) in your init method should work.

However, you should note that your textview is too small to show the table nicely and for displaying data like this a GtkListView in combination with a GtkTreeStore is better suited.
