  dataSource: {
    data: [
      { id: 1, name: "John", age: 25 },
      { id: 2, name: "Jane", age: 30 },
      { id: 3, name: "Bob", age: 35 }
    ],
    schema: {
      model: {
        id: "id",
        fields: {
          id: { type: "number" },
          name: { type: "string" },
          age: { type: "number" }
        }
      }

  columns: [
    { field: "id", title: "ID" },
    { field: "name", title: "Name" },
    { field: "age", title: "Age" }
  ],
  selectable: "cell", // 设置可选中单元格
  change: function(e) {
    // 获取选定单元格的值
    var selectedCell = this.select();
    var selectedDataItem = this.dataItem(selectedCell.closest("tr"));
    var selectedCellValue = selectedDataItem[this.columns[selectedCell.index()].field];
    
    console.log("选定的单元格值为：" + selectedCellValue);
  }
});
