title: How to apply a formula to an entire column in EPPLUS Core?
body: <p>I'd like to apply a formula to an entire column, even if I insert a new row, I need all cells from a certain column to have the formula in EPPLUS Core.</p>
  
  <p>For exemple, I would like to apply a formula to the column <code>C</code>.</p>
  
  <p>So every cell in column <code>C</code> (<code>C1,C2,...,C999999</code>) will have the formula</p>
