我正在编写spark datagrid,如下所示:

<s:DataGrid id="dgNews" x="10" y="150" width="300" height="545" color="#000000" visible="true" horizontalScrollPolicy="off" 
            variableRowHeight="true"  selectionColor="#e1ecf9" click="dgNews_clickHandler(event)">
    <s:columns>
        <s:ArrayList>               
            <s:GridColumn dataField="title" headerText="Technology" width="300"/>               
            <s:GridColumn dataField="content" headerText="Qty" width="198">
                <s:itemRenderer>
                    <fx:Component>
                        <s:GridItemRenderer>
                            <s:VGroup>
                                <s:Image source="{data.content}" height="198" width="198" >

                                </s:Image>                                  
                            </s:VGroup>

                        </s:GridItemRenderer>
                    </fx:Component>
                </s:itemRenderer>
            </s:GridColumn> 
        </s:ArrayList>
    </s:columns>
</s:DataGrid>

当我运行这个项目时,我得到了标题,但在图片栏中,我没有图片

或者我只是想在列中显示来自


有人能告诉我我做错了什么吗?

这是
内容
属性可绑定吗?图像的原始格式和url是我想要的url=“”。。。。
