title: Always display the first few lines of a buffer in Vim
body: <p>I often use gVim and Vim to view data tables in which the top row is the header. Is there any way to display this top row while browsing through the rest of the table? Ditto columns for the case in which the first column is a row heading.</p>
  <p><strong>EDIT:</strong> I accepted a good answer (and there were others) for showing the top column.</p>
  <p>The horizontal (first row) equivalent to the answer I accepted is</p>
  <pre><code>:vert split
  ctrl+w 5 |
  </code></pre>
  <p>or</p>
  <pre><code>ctrl+w v
  ctrl+w 10 |
  </code></pre>
  <p>It would be nice to be able to do both, but apparently that is not straightforward.</p>
