将表转换为datarow

Question

我想转换一下：

Province | Major                  | Qty
New York | Computer Science       | 4
New York | Information System     | 5
New York | Information Technology | 1
DC       | Information System     | 2
DC       | Information Technology | 3
Los      | Information System     | 4

到：

Province | Computer Science | Information System | Information Technology 
New York | 4                | 5                  | 1
DC       | 0                | 2                  | 3
Los      | 0                | 4                  | 0

这是我的代码：

    @model LPDPWebApp.Models.DKP.Chart5Model
<div class="col-md-6 grid">
    <div class="panel panel-grid">
        <div class="panel-heading">

        // Prevent the normal behavior since we opened the dialog
        e.preventDefault();
    });

    var randomScalingFactor = function () { return Math.round(Math.random() * 100) };

我得到了这个结果：

 Province | Computer Science | Information System | Information Technology 
    New York | 4                | 5                  | 1
    DC       | 0                | 2                  | 0                      | 3
    Los      | 0                | 4          

请帮助我，如何将原始数据转换为数据集的表数据？
