set border to listview Xamarin form - xaml

Question

I made a table with xamarin forms, but I would like the headers not to have blank spaces and also put borders, use table-striped, have the basic characteristics of a bootstrap table for example. Could you help me?. Thank you for you help.

you can do it like this:
<ListView ItemsSource="{Binding People}"
HasUnevenRows="True"
SeparatorVisibility="None">
<ListView.Header>
<Frame>
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Label Text="Name"
HorizontalOptions="Center"
FontSize="Large"/>
<Label Grid.Column="1"
Text="Description"
HorizontalOptions="Center"
FontSize="Large"/>
<BoxView Grid.Row="1"
Grid.ColumnSpan="2"
HeightRequest="1"
BackgroundColor="LightGray"/>
</Grid>
</Frame>
</ListView.Header>
<ListView.ItemTemplate>
<DataTemplate>
<ViewCell>
<Grid Margin="20,10">
<Grid.RowDefinitions>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<Grid.ColumnDefinitions>
<ColumnDefinition/>
<ColumnDefinition/>
</Grid.ColumnDefinitions>
<Label Text="{Binding Name}"
