title: Get foreground (font) in a particular JTable cell
body: <p>There are many answers to how to <em>set</em> the font (use renderer), but I want to <em>get</em> this font.  The reason why is for unit-testing: test for the renderer doing its job OK.</p>
  
  <p>The human eye can see whether a component for a given cell is rendered with a red foreground, but how can we do this programmatically?</p>
  
  <p><strong>later</strong><br> Just a word about my comment "get hold of the screen real estate". That's not quite it: each one of these table cells contains something... but what? And is it possible to reference it? It almost seems that each one is the "ghost" of the component (the same one) used successively to render each individual cell. Obviously I don't really know about the "architecture" of the representation of a JTable. Would be interesting to find out... although I suspect strongly that these "ghosts" (or whatever) are inaccessible.</p>
