title: How to format right and left justification on the same line?
body: <p>If I am making a data table to show the results of several functions, how can I use the setw(), left, and right keywords to create a table which is formatted like this:</p>
  
  <pre><code>Height                       8
  Width                        2
  Total Area                  16
  Total Perimeter             20
  </code></pre>
  
  <p>Notice how the overall "width" of the table is constant (about 20 spaces). But the elements on the left are left justified and the values on the right are right justified.</p>
