Drupal 8 的简单表格显示例子

有时候调试数据，需要表格呈现时，可参照以下例程。

  public function generate() {
    $teams = ['曼联', '曼城', '阿仙奴', '巴塞', '皇马', '拜仁'];
    $schedule = schedule($teams);
    $tables = [];
    foreach ($schedule as $key => $round) {
      $content = array(
        '#type' => 'table',
        '#sticky' => FALSE,
        '#header' => ['A队', 'B队'],
      );
      $rows = [];
      foreach($round as $match) {
        $rows[] = array($match[0], $match[1]);
      }
      $content['#rows'] = $rows;
      $tables[] = $content;
    }

    return $tables;
  }
