你可以使用单元格级别的数据绑定来给表格绑定数据。
表格的数据绑定为双向绑定。
如果你要给 表格 绑定一个数据源，你需要先给工作表绑定一个数据源，然后在 Table 类中设置 bindColumns 和 bindingPath 。
你可以使用 TableColumn 类中的 dataField 和 name 方法设置表格的属性。
数据绑定遵循以下规则：
- 在表格中修改数据将会触发数据同步操作
- 在表格中新增一条记录将会触发数据同步操作
- 添加或者删除列不会触发数据同步操作
- 删除表格，缩放，移动或清空表格不会触发数据同步操作
- 表格在绑定数据源时会自动调整行数（列数将保持不变）
- 表格中的公式不会被存入数据源。
参考代码
以下代码给表格绑定了一个数据源。
