如何以编程方式设置或更改具体单元格的值？

Question

使用纯数组作为数据源（而不是DateView）来初始化SlickGrid，我想在特定行/列（单元格）上创建网格后更改值。

这是一个简单的例子，也可以作为working JSFiddle找到，我想要例如将第3行（“任务2”）的“持续时间”的值从“5天”更改为“7天”。

<div id="myGrid" style="width:400px;height:400px;"></div>   

<script>
  var grid;
  var columns = [
    {id: "title", name: "Title", field: "title"},
    {id: "duration", name: "Duration", field: "duration"},
    {id: "%", name: "% Complete", field: "percentComplete"},
    {id: "start", name: "Start", field: "start"},
    {id: "finish", name: "Finish", field: "finish"},
    {id: "effort-driven", name: "Effort Driven", field: "effortDriven"}
  ];

  var options = {
    enableCellNavigation: true,
    enableColumnReorder: false
  };

  $(function () {
    var data = [];
    for (var i = 0; i < 500; i++) {
      data[i] = {
        title: "Task " + i,
        duration: "5 days",
        percentComplete: Math.round(Math.random() * 100),
        start: "01/01/2009",
        finish: "01/05/2009",
        effortDriven: (i % 5 == 0)
      };
    }

    grid = new Slick.Grid("#myGrid", data, columns, options);
    grid.setSelectionModel(new Slick.CellSelectionModel());

    /* needed method */
    grid.setCellValue(2, 1, "7 days");
    /* or */
    grid.setCellValue(2, "duration", "7 days");

  })
</script>

它看起来像一个方法

grid.setCellValue(row, column, value);

不存在。

有没有一种方法（或者我还没有发现的现有方法）在不使用DataView的情况下实现这一目标？
