添加<一href="http://msdn.microsoft.com/en-us/library/system.windows.controls.primitives.thumb.aspx">Thumb控制到模板。您还没有公布模板标记code，但你可以检查的这个帖子获取完整的例子。

How come whenever I override the default template for a DataGridColumnHeader it can no longer be resized by the user even though CanUserResizeColumns is set to true for the datagrid? Is there something that I need to add to the template to restore this functionality?

Here's my template xaml:

<Style x:Key="ColumnHeaderStyle" TargetType="{x:Type DataGridColumnHeader}">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="DataGridColumnHeader">
                    <Border BorderThickness="1" Margin="-1,0,0,0"  Background="#f9f9f9" BorderBrush="Gray">
                        <Grid>
                            <TextBlock Margin="2" Text="{TemplateBinding  Content}"  VerticalAlignment="Center" 
                                HorizontalAlignment="Left"  TextWrapping="Wrap"/>                           
                        </Grid>
                    </Border>                        
                </ControlTemplate>
            </Setter.Value>
        </Setter>
</Style>

解决方案

Add the Thumb control to the template. You haven't posted template markup code, but you can check this post for complete example.
