<xhtml:div component="/UI/system/components/grid.xbl.xml#grid" data="dataMain"
      id="grdMain" show-header-menu="hide-column,save-layout,group-column,adjust-column">
      <xui:column id="gridColumn1" ref="D_BillDate" label="日期" type="ed" width="100px"/>  
      <xui:column id="gridColumn2" ref="i_stockInNum" label="数量" type="ed" width="100px"/>
    </xhtml:div>
是像这样吗？
