Closest thing you can do is put two spaces in front of every line and monospace it:

  Nation          Total Fertility Rate 
  ------------------------------------
  Australia       1.97
  Austria         1.41
  Canada          1.58 
  Czech Republic  1.49 
  Finland         1.85
  Ireland         2.1 
  Netherlands     1.66 
  New Zealand     2.1 
  Switzerland     1.46
