Xamarin 的 GridLayout 问题

Question

 <Grid
                                Margin="30,30,30,30"
                                BackgroundColor="{StaticResource ColorBack002}"
                                RowSpacing="40">
                                <Grid.ColumnDefinitions>
                                    <ColumnDefinition Width="3*" />
                                    <ColumnDefinition Width="7*" />
                                </Grid.ColumnDefinitions>


                                <Grid.RowDefinitions>

                                <!--#endregion-->

我有这样的布局。我将 TextEdit 的 HorizontalOption 设置为 FillAndExpand。 在屏幕上，TextEdit 的提示被切断了大约 1 个像素。为什么会这样？

Textedit 似乎被扩展以适应屏幕，但它似乎已经扩展到更远的地方。
