$config['koolreport'] = array(
    'defaultDataSource' => 'default',
    'defaultLayout' => 'default',
    'assetsPackage' => 'default',
    'reportingSystem' => 'koolreport',

                'password' => 'your_password',
                'dbname' => 'your_database'
            )
        )
    )
);

<?php

require_once APPPATH . 'third_party/koolreport/autoload.php';

use \koolreport\KoolReport;

class MyReport extends KoolReport
{
    public function settings()
    {
        return array(

            )
        );
    }

    public function setup()
    {
        // 在这里设置您的报表
    }
}

public function index()
{
    $report = new MyReport;
    $report->run();
    $data['output'] = $report->render();
    $this->load->view('report_view', $data);
