片段 <probe:RowColorDataGrid x="6" y="335" itemClick="itemClick(event)" rowCount="5" dataProvider="{dataArr}" width="760" color="#2750A5" id="DataGrid1"> <probe:columns> <mx:DataGridColumn headerText="序号" dataField="id" width="29"/> <mx:DataGridColumn headerText="时间" dataField="time" width="136"/> <mx:DataGridColumn headerText="经度" dataField="lat" width="74"/> <mx:DataGridColumn headerText="纬度" dataField="lon" width="74"/> <mx:DataGridColumn headerText="光强" dataField="photoelectricity" width="32"/> <mx:DataGridColumn headerText="压力" dataField="pressure" width="32"/> <mx:DataGridColumn headerText="湿度" dataField="humidity" width="32"/> <mx:DataGridColumn headerText="温度" dataField="temperature" width="32"/> <mx:DataGridColumn headerText="速度" dataField="speed" width="32"/> <mx:DataGridColumn headerText="状态" dataField="info" width="96"/> <mx:DataGridColumn headerText="其他" dataField="other" width="96"/> </probe:columns> </probe:RowColorDataGrid>   只要修改RowColorDataGrid.rowId就行
