我有与此问题相同的问题：

DataGrid列标题与数据不对齐

我所拥有的是窗口中但在scrollviewer内部的datagrid。我想做的是将带有此datagrid的scrollviewer转移到另一个窗口。现在它可以正常工作，但是我的数据网格在另一个窗口中未正确对齐。有什么原因可以解决这个问题？PS：如果你需要提供任何代码，请告诉我。

更新：

<ScrollViewer Grid.Row="1" Name="inputReportScrollViewer" Height="22cm" Width="19cm" HorizontalAlignment="Center" >

<Grid>
   <Grid.RowDefinitions>
     <RowDefinition Height="auto" />
   </Grid.RowDefinitions>

   <Grid Grid.Row="0">
                <DataGrid Name="InputReportDataGrid"  AutoGenerateColumns="False" CanUserAddRows="false" >
