2
 * Add a new row to the table and display it on the screen by jumping the
3
 * pagination to the required location. This function also returns an object
4
 * with the added `dt-tag TR` element and it's index in `aoData` such that you
5
 * could provide an effect (fade for example) to show which row has been added.
6
 *
7
 * This function is a drop in replacement for `fnAddData` with one important
8
 * exception, it will only take a 1D array or an object, and not a 2D array
9
 * (i.e. it will not add multiple rows like `fnAddData`).

 *  @name fnAddDataAndDisplay

 *  @param {data} aData Data to add to the table
16
 *  @returns {object} Object with `nTr` and `iPos` parameters, where the former
17
 *    is the added `dt-tag tr` element and the latter is the row's index.
