title: Excel formula: How to refer a cell by its column name
body: <p>How can I change my excel formula if I need to replace direct reference to the cell by the column name of this cell? For example, instead of</p>
  <pre><code>SUM(A1:B1)
  </code></pre>
  <p>I want to use something like</p>
  <pre><code>SUM({Column1}:{Column2})
  </code></pre>
  <p>I know about structured reference, but I can not convert my excel dataset into named table.
  Do I have any options?</p>
