Hello,
I am trying to make DataTables work with rowDetailData and serverSide: true. However, it seems that serverSide: true and rowDetailData are incompatible.
Here after my code
**************** Test1.php *********************************
<?php
require_once "../koolreport/core/autoload.php";
class Test1 extends \koolreport\KoolReport
{
    function settings()
    {
        return array(
            "dataSources"=>array(
                "automaker"=>array(
                    "connectionString"=>"mysql:host=localhost;dbname=automaker",
                    "username"=>"root",
                    "password"=>"",
                    "charset"=>"utf8"
                ),
            )
        ); 
    } 
    protected function setup()
    {
        $this->src('automaker')
        ->query('select * from customers')
        ->pipe($this->dataStore("TestRowDetail_WithServerSide"));
    }  
}
**************************************************************
**************** Test1.view.php ***************************
<?php
    use \koolreport\datagrid\DataTables;
?>
<div class="report-content">
    <div class="text-center">
        <h1>DataTables</h1>
        <p class="lead">How to use row detail with DataTables</p>
    </div>
	
    <?php
    DataTables::create(array(
	    "name" => "MyTbl123",		
		"emptyValue"=> "", 
        "dataSource"=>$this->dataStore("TestRowDetail_WithServerSide"),
        "themeBase"=>"bs4", 
		/*************************/
		//"serverSide"=> true,
		/*************************/
		"method"=>'post',
		"processing"=> true,
        "columns" => [
            "customerName", "phone", "city", "postalCode",
            "country" => ["visible" => false,]
        ],       
        "options" => [
            "searching"  => true,
            "paging"     => true,
            "pagingType" => "input",          
            "pageLength" => 10,						
        ],
		"rowDetailData" => function($row) {
            return "country: " . $row["country"];
        },
    ));
    ?>
</div>
*************************************************************
When "serverSide"=> true, is commented, it works fine. Whene it's commented out it does work, I got a warning
DataTables warning: table id=MyTbl123 - Requested unknown parameter '5' for row 0, column 5. For more information about this error, please see http://datatables.net/tn/4
and the table is not well displayed

Any help please?
Thanks
