/**
|
|
* 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 `dt-tag 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`).
|
|
*
|
|
* @name fnAddDataAndDisplay
|
|
* @summary Add data and shift the paging to display it immediately

|
|
* @param {data} aData Data to add to the table
|
|
* @returns {object} Object with `nTr` and `iPos` parameters, where the former
|
|
* is the added `dt-tag tr` element and the latter is the row's index.
|
|
*
|
|
* @example
|
|
* $(document).ready(function() {
|
|
* var table = $('#example').dataTable();
|
|
* table.fnAddDataAndDisplay( [ 1, 2, 3, 4, 5, ... ] );
|
