【CodeIgniter3(コードイグナイター)】のテーブルヘルパー(列数を統一して空白のtdを埋める)

$this->load->library('table');

$table = array(
    'table_open' => '<table class = "tableLine all-center">',
);
$th = array('会員ID', '名前', '年齢');
$td = array('one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight');
if(count($td)%3 > 0){
    array_push($td, '調査中');
    if(count($td)%3 === 2){
        array_push($td, '調査中');}
}

$this->table->set_template($table);
$this->table->set_heading($th);
$new_list = $this->table->make_columns($td, 3);
echo $this->table->generate($new_list);

結果
