Get result from another column

[nitinsonawane234]

Hello,
I just want to get the result from another column and put it into next column for calculation and to save execution time.

example:

echo TreeGrid::widget([
	'dataProvider' => $dataProvider,
	'keyColumnName' => 'id',
	'parentColumnName' => 'PARENT_ID',
	'parentRootValue' => '', //first parentId value
	'pluginOptions' => [
		'initialState' => 'expanded', //collapsed
	],
	'columns' => [
		[
			'attribute' => 'JAN',
			'value' => function($model, $key, $index, $grid){
				$model['MONTH'] = 1;
				$resultJan = $model->bALANCE;
				return $resultJan;
			},
		],
		[
			'attribute' => 'FEB',
			'value' => function($model, $key, $index, $grid) use ($resultJan){
				$model['MONTH'] = 2;
				return $resultJan+$model->bALANCE;
			},
		],
	]     
]);

So, Here I want to use $resultJan into FEB column.

Got the answer.
Ex:
class Test extends ActiveRecord{ public $custom_attribute; ... }
And at TreeGrid you must:
'value' => function($model, $key, $index, $grid){ $model['MONTH'] = 1; $resultJan = $model->bALANCE; $model->custom_attribute = $resultJan; return $resultJan; }
