db7877b089ad41f8aebc49c0810c81adc5c44cacLuke Smith    The output structure is basically a simulation of the `<thead>` structure
db7877b089ad41f8aebc49c0810c81adc5c44cacLuke Smith    with arrays for rows and objects for cells.  Column objects have the
db7877b089ad41f8aebc49c0810c81adc5c44cacLuke Smith    following properties added to them:
db7877b089ad41f8aebc49c0810c81adc5c44cacLuke Smith

71119127902d812c7eabcc0c483993295b0cce20Luke Smith      * `_parent`  - (Added by DataTable) If the column is a child of another
71119127902d812c7eabcc0c483993295b0cce20Luke Smith        column, this points to its parent column
db7877b089ad41f8aebc49c0810c81adc5c44cacLuke Smith
db7877b089ad41f8aebc49c0810c81adc5c44cacLuke Smith    The column object is also used to provide values for {placeholder}
db7877b089ad41f8aebc49c0810c81adc5c44cacLuke Smith    replacement in the `CELL_TEMPLATE`, so you can modify the template and
db7877b089ad41f8aebc49c0810c81adc5c44cacLuke Smith    include other column object properties to populate them.
