What is Placeholder in header ?

So I have 2 questions. I have been searching through the official docs but no luck. 1. How do we set the isPlaceholder as true or false for particular header ? 2. What is placeholder header used for ? I am guessing its used for not rendering any specific content or keep the header blank ? I am defining column like this. How do we set the header as placeholder header so that while rendering actual table header.isPlaceholder can be evaluated as true. 
  let predefColumn = {
    accessorKey: '_empty',
    cell: () => {},
    header: () => {},
    maxSize: 4,
    enableSorting: false,
  };
  let predefColumn = {
    accessorKey: '_empty',
    cell: () => {},
    header: () => {},
    maxSize: 4,
    enableSorting: false,
  };
Please if someone can elaborate more on this, would be really really appreciated ! Thanks !

As as I understand the code of createHeaderGroup function, isPlaceholder is used to help build the HeaderGroup. It controls whether or not to display a header of column in the current group.
