	 *       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:

	 *         <li>{string} The type call data requested - this will be 'set' when

	 *           gathering data. Note that when <i>undefined</i> is given for the type

	 *         <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

	/**

	 * is that "mmm" is much wider then "iiii", but the latter is a longer 
	 * string - thus the calculation can go wrong (doing it properly and putting
	 * it into an DOM object and measuring that is horribly(!) slow). Thus as
	 * a "work around" we provide this option. It will append its value to the
	 * text that is found to be the longest string for the column - i.e. padding.
