It doesn't for now but you can overcome it with a simple solution like this:

$datastore = new new \koolreport\core\DataStore();
$datastore->data($arrData);
$datastore->meta($meta); // $meta could be an empty array []
\koolreport\excel\Table::create(array(
    "dataSource" => $datastore,
    ...

Pls try it and let us know if you have any trouble. Tks,

Just include "\n" in your footerText if you want a new line like this:

  "footerText"=>"Total: @value \n Total Approved CPD Points :  20", //remember to use \n in double quotes for new line meaning, in single quotes \n is just \n
