       <!--三种方法在DataGrid上显示toolTip，此DataGrid上共显示了三列，前两列需要将showDataTips属性设为true！！

          第一列采用设置列属性dataTipField的方式来显示toolTip，本示例中可以设为：name，phone，email或active；

           第二列采用设定Tip函数dataTipFunction的方式来显示，此函数默认会获取本列绑定的数据作为参数，所以不需指定；

           第三列采用itemRenderer的方式，给其中的控件指定toolTip来达到目的，此处用的是Text，用label会更好一些，

           在内容显示不全的时候，label会自动显示toolTip，无需指定。-->
