title: Org mode table, show different background on current row, or, alternate even/odd org rows
body: <p>On wider tables in org mode, it is hard to see the current line.</p>
  
  <p>In emacs org mode table, is there a way to display different background for the current row, or alternate background for even/odd rows? </p>
  
  <p>(I am not concerned with export, although if the even/odd alternate background would export that would be great as well)</p>
  
  <p>Thanks</p>
