The example demonstrates usage of CopyColumn process. The CopyColumn process is used to duplicate data of an existed column. This CopyColumn is important when you want to make a copy then do something with duplicated column without losing the original data.
<?php
require_once "MyReport.php";
$report = new MyReport;
$report->run()->render();
<?php
//Step 1: Load KoolReport
require_once "../../../load.koolreport.php";
use \koolreport\processes\ColumnMeta;
use \koolreport\processes\CopyColumn;
//Step 2: Creating Report class
class MyReport extends \koolreport\KoolReport
