title: Is it possible to cross out cells in an HTML table?
body: <p>I want to create an HTML table in which I am able to cross out cells as shown in the following drawing:</p>
  
  <p><img src="https://i.stack.imgur.com/zEQCY.png" alt="Table with crossed out cells"></p>
  
  <p>I originally thought about doing a CSS right triangle in the cell, but I couldn't figure out how to color just the hypotenuse and not the other two sides or the triangle itself.</p>
  
  <p>In other words, is what I want to do possible?<br>
  Would making an image with a diagonal line and then making that image stretch 100% the width and height of the cell make the most sense?<br>
  Thanks.</p>
