In following example we would be combining Grid Layout + Stack Panel Layout. This would give us effect of Table control and Span Control of HTML.
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="60"/>
<RowDefinition Height="40"/>
<RowDefinition Height="40"/>
<RowDefinition Height="40"/>
<RowDefinition Height="40"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock x:Name ="Nesting Layout Demo"
FontSize="15" FontWeight="Bold"
Foreground="Blue"
Grid.Column="0" Grid.Row="0" Grid.ColumnSpan="3"/>
<StackPanel Grid.Column="0" Grid.Row="1" Orientation="Horizontal">
<TextBlock Text="Name" FontSize="25" FontWeight="Bold" />
<TextBox x:Name="txtName" Text="Query Home" VerticalAlignment="Bottom" Height="76" Margin="0,-21,0,-15" Width="281"/>
</StackPanel>
<StackPanel Grid.Column="0" Grid.Row="3" Orientation="Horizontal" Margin="10,30,-10,10" Grid.RowSpan="2">
<TextBlock Text="City" FontSize="25" FontWeight="Bold" Width="52"/>
<TextBox x:Name="txtCity" Text="Bangalore" VerticalAlignment="Center" Width="300" Height="70" Margin="0,-30,0,0"/>
</StackPanel>
<StackPanel Grid.Column="0" Grid.Row="4" Orientation="Horizontal" Margin="0,66,0,-66">
<TextBlock Text="State" FontSize="25" FontWeight="Bold"/>
<TextBox x:Name="txtState" Text="Karnataka" VerticalAlignment="Center" Width="295" Height="70" Margin="0,0,0,-30" RenderTransformOrigin="0.616,0.485"/>
</StackPanel>
