Create Xlsx Files With Auto Column Width Settings

Code an xlsx file in PhpSpreadsheet to automatically adjust a column width based on the maximum number of characters from a cell within the given column. Once the xlsx file is created, the cell will automatically fit it’s value, this is similar to manually setting the column width with the function ‘Auto Fit Column Width’.
