title: Julia Create Column name from a variable when writing to a csv file
body: <p>I'm trying to write a column name which has a variable. The other thing Im trying to get is the append function column-wise.</p>
  <pre><code>CSV.write(&quot;File_Name.csv&quot;,(;&quot;column$i&quot;::String=sort(val)),append=true)
  </code></pre>
  <p>where i is generated in for loop.
  Also, how to append in next column? e.g. if there are 2 columns</p>
  <blockquote>
  <p>column 1 | column2 |</p>
  </blockquote>
  <p>then whats the way to add new column next to them as column 3?</p>
