title: Connect Table Cells from Different Rows with Diagonal line
body: <p>I'm looking to have diagonal lines connecting table cells from different rows.  I can easily get a diagonal line to connect the corners of a single cell, but is there a way to cross cells?</p>
  <p>For example, in the image below, I'd like to have diagonal lines connecting &quot;1 and &quot;3&quot; to the &quot;1 &amp; 3&quot; cell.  Same thing with 2, 5, and 2 &amp; 5.</p>

  <p>Of course, this is just one variation.  I would like to be able to connect any number of cells in any way.  Maybe something like this...</p>

  <p>Any ideas here?</p>
