WPF DataGrid设置字体居中

xaml：

先加
<Window.Resources>
        <ResourceDictionary>
            <Style x:Key="dgCell" TargetType="TextBlock">
                <Setter Property="TextAlignment" Value="Center"/>
            </Style>
        </ResourceDictionary>
    </Window.Resources>

再加：ElementStyle="{StaticResource dgCell}"

 <DataGrid Name="dgBuild" ItemsSource="{Binding}"  HorizontalScrollBarVisibility="Hidden"  AutoGenerateColumns="False"  CanUserReorderColumns="False" HeadersVisibility="None"  GridLinesVisibility="All"  HorizontalGridLinesBrush="#000" IsReadOnly="True"  HorizontalAlignment="Center" >
                <DataGrid.Columns   >
                    <DataGridTextColumn Width="*"   Binding="{Binding ItemName}" ElementStyle="{StaticResource dgCell}"/>
                    <!--<DataGridTextColumn Binding="{Binding Class}"/>-->
                    <DataGridTextColumn Width="*" Binding="{Binding Data}"  ElementStyle="{StaticResource dgCell}"/>
                </DataGrid.Columns>
            </DataGrid>
