  • label is the header of the column. If missing label, field.verbose_name or function.short_description will be used firstly. If still null, use the field name.
  • render is a callable object that transform the original value to display value.
  • empty_value only works when render is not provided, it is the display value for orignal None value.
  • footer-value is the value display at the bottom row. It can be an instance of Aggregate that accept every item value of this field and calc the final value at last. It can be a staic value.
  • start-row-index is row index where begin to write data. starts from 1.
  • xlsx-template template xlsx file path.
  • show-header True or False means show header or not.
