title: Is there a built-in way to convert a column number to an Excel column with Laravel Excel
body: <p>I want to add some style on a column using Laravel Excel. I know this column is the (let's say) 42nd, but I don't know the Excel code (like <code>AA</code>, <code>BC</code>, etc.). </p>
  
  <p>I know I can build a function (based on <a href="https://stackoverflow.com/questions/181596/how-to-convert-a-column-number-eg-127-into-an-excel-column-eg-aa">this answer</a>) to convert the column number to a letter, but I not sure it's the right way.</p>
