/**
* Creates `rowspan` cells in a column when there are two or more cells in a
* row with the same content, effectively grouping them together visually.
*
* **Note** - this plug-in currently only operates correctly with
* **server-side processing**.
*
* @name fnFakeRowspan
* @summary Create a rowspan for cells which share data
* @author Fredrik Wendel
*
* @param {interger} iColumn Column index to have row span
* @param {boolean} [bCaseSensitive=true] If the data check should be case
* sensitive or not.
* @returns {jQuery} jQuery instance
*
* @example
* $('#example').dataTable().fnFakeRowspan(3);
