title: Is there a good emacs mode for displaying and editing huge delimiter separated files?
body: <p>I've been searching without finding for a while for a mode that makes editing huge tab/comma/colon-separated files easy. I've been wanting a mode that ensures that columns always line up, just like org-mode tables. I know I can easily turn the whole file into an org-mode table and then turn it back when I'm done, but that gets really slow with huge files, and is a hassle for quick edits (there's also the problem of what happens if a field contains a vertical bar). So does anyone know of either a mode or a built-in function/variable I can use so that I can get a file like</p>
  
  <pre><code>col1\tcol2\tcol3
  very long column1\tcol2\tcol3
  </code></pre>
  
  <p>displayed like</p>
  
  <pre><code>col1               col2  col3
  very long column1  col2  col3
  </code></pre>
  
  <p>? (perhaps with some color lining the separator)</p>
