将OData连接到表以动态创建行

Question

我无法将OData连接到普通表以动态创建行。我的以下代码用于正常创建不带OData的行。

var aColumnData = [
  {
    columnId: "col1"
  },
  {
    columnId: "col2"
  },
  // ...
];
var aData = [
  {
    col1: "Row 1 col 1",
    col2: "Row 1 col 2",
    // ...
  },
  {
    col1: "Row 2 col 1",
    col2: "Row 2 col 2",
    // ...
  },
  // ...
];
var oModel = new JSONModel(); // required "sap/ui/model/json/JSONModel"
oModel.setData({
  columns: aColumnData,
  rows: aData
});
var oTable = this.getView().byId("usertable");
oTable.setModel(oModel);
oTable.bindColumns("/columns", function(index, context) {
  var sColumnId = context.getObject().columnId;
  return new Column({ // required "sap/ui/table/Column"
    label: sColumnId,
    template: sColumnId
  });
});
oTable.bindRows("/rows");

如何通过读取OData服务的元数据获得相同的结果？
