  1. Thank you!
    Great tutorial on arrays in Yii2.
    I have a query in mysql that want to display the result in the same way.

    Here is the table:
    CREATE TABLE Sales (empID INT, yr SMALLINT, sales DECIMAL(10,2));
    INSERT sales VALUES
    (1, 2005, 12000),(1, 2006, 18000),(1, 2007, 25000),
    (2, 2005, 15000),(2, 2006, 6000),(3, 2006, 20000),(3, 2007, 24000);

    and this query in mysql:
    1. In an inner query, write one aggregating expression per reporting column,
    2. In an outer query, build the horizontal sums:

    SELECT
    IFNULL(empId,'Totals') AS EmpId, -- outer query labels rollup row
    sums.2005, sums.2006, sums.2007, -- and calculates horizontal sums
    sums.2005 + sums.2006 + sums.2007 AS Sums
    FROM ( -- inner query groups by employee
    SELECT -- with an expression for each column
    EmpID,
    SUM(IF(Yr=2005,sales,0)) As '2005',
    SUM(IF(Yr=2006,sales,0)) As '2006',
    SUM(IF(Yr=2007,sales,0)) As '2007'
    FROM Sales
    GROUP BY EmpID WITH ROLLUP
    ) AS sums;

    And want to show the following table:
    +--------+----------+----------+----------+-----------+
    | EmpId | 2005 | 2006 | 2007 | Sums |
    +--------+----------+----------+----------+-----------+
    | 1 | 12000.00 | 18000.00 | 25000.00 | 55000.00 |
    | 2 | 15000.00 | 6000.00 | 0.00 | 21000.00 |
    | 3 | 0.00 | 20000.00 | 24000.00 | 44000.00 |
    | Totals | 27000.00 | 44000.00 | 49000.00 | 120000.00 |
    +--------+----------+----------+----------+-----------+

      return $this->render('index', [

      }

    2. //Index page of display in grid view


      echo GridView::widget([
