         *   <ul>
         *     <li>integer - treated as an array index for the data source. This is the
         *       default that DataTables uses (incrementally increased for each column).</li>
         *     <li>string - read an object property from the data source. Note that you can
         *       use Javascript dotted notation to read deep properties/arrays from the
         *       data source.</li>
         *     <li>null - the sDefaultContent option will be used for the cell (null
         *       by default, so you will need to specify the default content you want -
         *       typically an empty string). This can be useful on generated columns such 
         *       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 
         *           gathering data. Note that when <i>undefined</i> is given for the type
         *           DataTables expects to get the raw data for the object back</li>
         *         <li>{*} Data to set when the second parameter is 'set'.</li>
         *       </ul>
         *       The return value from the function is not required when 'set' is the type
         *       of call, but otherwise the return is what will be used for the data
         *       requested.</li>
         *    </ul>
         *
         * Note that prior to DataTables 1.9.2 mData was called mDataProp. The name change
         * reflects the flexibility of this property and is consistent with the naming of
         * mRender. If 'mDataProp' is given, then it will still be used by DataTables, as
         * it automatically maps the old name to the new if required.
