title: How can I set NSTableView column to use monospaced numbers?
body: <p>El Capitan introduced San Francisco system font, which has proportional digits by default.</p>
  
  <p>This makes numbers in table columns look jagged and hard to compare: </p>

  <p>I'd like to enable fixed-width numbers option for the font, but keep using the default system font and keep backwards compatibility with earlier versions of OS X. </p>
  
  <p>In Interface Builder selecting font > Font Panel > Typography > Monospaced Numbers <em>does not</em> affect the font (XIB file remains unchanged).</p>

  <p>What's the right way to set monospaced numbers in OS X table view columns? (I suspect IB is unusable for this, so a programmatic solution is OK too).</p>
