Add data and shift the paging to display it immediately

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).

Plug-in code

jQuery.fn.dataTableExt.oApi.fnAddDataAndDisplay = function ( oSettings, aData )
    /* Add the data */
    var iAdded = this.oApi._fnAddData( oSettings, aData );
    var nAdded = oSettings.aoData[ iAdded ].nTr;

    /* Need to re-filter and re-sort the table to get positioning correct, not perfect
     * as this will actually redraw the table on screen, but the update should be so fast (and
     * possibly not alter what is already on display) that the user will not notice
    this.oApi._fnReDraw( oSettings );

    /* Find it's position in the table */
    var iPos = -1;
    for( var i=0, iLen=oSettings.aiDisplay.length ; i<iLen ; i++ )
        if( oSettings.aoData[ oSettings.aiDisplay[i] ].nTr == nAdded )
            iPos = i;

    /* Get starting point, taking account of paging */
    if( iPos >= 0 )
        oSettings._iDisplayStart = ( Math.floor(i / oSettings._iDisplayLength) ) * oSettings._iDisplayLength;
        if ( this.oApi._fnCalculateEnd ) {
            this.oApi._fnCalculateEnd( oSettings );

    this.oApi._fnDraw( oSettings );
    return {
        "nTr": nAdded,
        "iPos": iAdded
