+ * Get a `dt-tag td` node from a row, taking into account column visibility.
+ * While getting a `dt-tag td` node is easy when it is visible on the page by
+ * using normal DOM methods, jQuery or whatever, it becomes a lot more
+ * complicated when taking into account hidden rows and columns. This function
+ * can be used to overcome these difficulties.
+ *
+ * DataTables 1.10+'s new API provides the `dt-api cell()` and `dt-api cells()`
+ * methods which are preferable for use over this method. As such this method is
+ * marked deprecated, but is available for use with legacy version of
+ * DataTables. Please use the new API if you are used DataTables 1.10 or newer.
