        <Grid.RowDefinitions>
            <RowDefinition Height="100"/>
            <RowDefinition Height="300"/>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>

            <ColumnDefinition Width="2*"/>
            <ColumnDefinition Width="4*"/>
        </Grid.ColumnDefinitions>

2.4 自动分配

- 某一行或某一列不存在内容，则不为其分配空间。

        <Grid.RowDefinitions>
            <RowDefinition/>
            <RowDefinition/>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="auto"/>
            <ColumnDefinition/>
            <ColumnDefinition/>
        </Grid.ColumnDefinitions>
