- * <li>null - the sDefaultContent option will be used for the cell (null

- * as edit / delete action columns.</li>
- * <li>function - the function given will be executed whenever DataTables
- * needs to set or get the data for a cell in the column. The function
- * takes three parameters:
- * <ul>
- * <li>{array|object} The data source for the row</li>
- * <li>{string} The type call data requested - this will be 'set' when
- * setting data or 'filter', 'display', 'type', 'sort' or undefined when

- * DataTables expects to get the raw data for the object back</li>

- * Note that prior to DataTables 1.9.2 mData was called mDataProp. The name change
