title: Set header when creating table from CSV
body: <p>I have a csv "pf.csv":</p>
  
  <pre><code>Jules,Winnfield  
  Vincent,Vega  
  Mia,Wallace  
  Marsellus,Wallace  
  </code></pre>
  
  <p>And would like to specify a list of symbols which become the header when I read the csv. Normally I would load the csv like so:</p>
  
  <pre><code>("SS";enlist ",") 0: `$"pf.csv"
  </code></pre>
  
  <p>but that actually sets the first row as the keys in the flipped dictionary (i.e. the header in the table)<br>
  In the <a href="https://code.kx.com/wiki/Reference/ZeroColon" rel="nofollow noreferrer">documentation</a> for <code>0:</code> I read</p>
  
  <blockquote>
    <p>Optionally, 0: can take a three-item list as its second argument,
    containing the file handle, an offset at which to begin reading, and a
    length to read.</p>
  </blockquote>
  
  <p>But that's inconvenient as the offset has to be given in number of characters and not in lines. </p>
