GridView中几个显示数据时! 数据停靠(靠左 or 居中)的问题!

1.假如下面有一个Gridview,

<asp:GridView ID="GVData" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False"
                    BorderStyle="Solid" BorderWidth="1px" OnRowDataBound="GVData_RowDataBound" PageSize="15"
                    Width="100%" CssClass="gridview">
                    <PagerSettings Mode="NumericFirstLast" Visible="False" />
                    <PagerStyle BackColor="LightSteelBlue" HorizontalAlign="Right" />
                    <HeaderStyle BackColor="#006599" Font-Size="12px" ForeColor="White" Height="20px" />
                    <AlternatingRowStyle BackColor="WhiteSmoke" />

                       <asp:BoundField DataField="Address" HeaderText="收货地址">
                        <ItemStyle HorizontalAlign="Left" />                --使包含这个属性的列居左边
                        </asp:BoundField>

<asp:BoundField DataField="ShippingMobile" HeaderText="收货电话" /> --居中

</Columns>
<RowStyle HorizontalAlign="Center" Height="25px" /> --使整个Gridview的行默认居中

</asp:GridView>
