我有一个值表，其中填充了一系列月份名称和总和。如何计算行和列中这些值的总和，并在结果列中的结果字符串中显示结果？ table

public function getReport($year=false)
    {

这段代码转到你的视图文件

'columns'=>array(
                ..........
                array(
                        'name'=>'age',
                        'footer'=>'Total: ' . $model->getTotal($model->search()->getData(), 'age'),
                ),
                array(
                        'name'=>'weight',
                        'footer'=>'Total: ' . $model->getTotal($model->search()->getData(), 'weight'),
                ),
                ..........
        ),

，这个转到您的模型文件

 public function getTotal($records, $column)
        {
                $total = 0;
                foreach ($records as $record) {
                        $total += $record->$column;
                }
                return $total;
        }
