只要引入这个“命名空间”就会报错：

xmlns:sdk="http://schemas.microsoft.com/winfx/2006/xaml/presentation/sdk"

你好，

DataGridTemplateColumn.CellTemplate没有Header属性，你只要改成如下所示即可：

<sdk:DataGridTemplateColumn Header="项目" >
                        <sdk:DataGridTemplateColumn.CellTemplate >
                            <DataTemplate>
                                <StackPanel  Orientation="Vertical">
                                    <TextBlock Text="能耗量合计"></TextBlock>
                                    <TextBlock Text="单位面积能耗"></TextBlock>
                                    <TextBlock Text="生均能耗"></TextBlock>

                                </StackPanel>
                            </DataTemplate>
                        </sdk:DataGridTemplateColumn.CellTemplate>
                    </sdk:DataGridTemplateColumn>
