There is MyModelSearch
In the public function search($params) method
I write $query = MyTable::find() ->.... , and I receive dataProvider .
In the view in the GridView passed this dataProvider and display all the columns from the table MyTable .
For example, 40 entries are displayed in the temperature column.
How to separate the value of the Count(temperature > 10) from the GridView on the page Count(temperature > 10) ?
