/**
|
|
* Add a new row to the table and display it on the screen by jumping the
|
|
* pagination to the required location. This function also returns an object
|
|
* with the added TR element and it's index in aoData such that you could
|
|
* provide an effect (fade for example) to show which row has been added.
|
|
* This function is a drop in replacement for fnAddData with one important
|
|
* exception, it will only take a 1D array or an object, and not a 2D array
|
|
* (i.e. it will not add multiple rows like fnAddData).
