Answer 1

gridview本身就是表格，你没有必要自己加入
 <tr>
                                   <td colspan="100%">
 </td>
 </tr>

Answer 2

因为我要用表格去控制他的样式，如果不用表格的话，两个GRIDVIEW就是左右并列显示的，但是我用了之后，他上线显示成父子的形式了，但是还是每行都 有一个很大的缝隙

Answer 3

用是可以的，你需要使用正确啊
  <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" OnRowDataBound="GridView1_RowDataBound">
    <Columns>
      <asp:TemplateField>
        <ItemTemplate>
          <table>
            <tr>
              <td>
                <asp:GridView ID="Gr2" runat="server">
                </asp:GridView>
              </td>
              <td>
                <asp:GridView ID="GridView2" runat="server">
                </asp:GridView>
              </td>
            </tr>
          </table>
        </ItemTemplate>
      </asp:TemplateField>
    </Columns>
  </asp:GridView>

Answer 4

这样就跑偏了，跑右边去了，我想实现的是一个GridView在另一个的下面（垂直方向），实现父子的效果？

Answer 5

DataGrid就是个害人不浅，我就是被它害成现在这样的。
楼主深思！

Answer 6

把HTML代码发出来看看 这个看不来效果
