Binding of Multiple DataGrid Column Header

I came across this code sample at TechNet witch shows how to bind a single column header title and its corresponding columns data :

<DataGrid ItemsSource="{Binding Items}" AutoGenerateColumns="False">
    <DataGrid.Columns>
        <DataGridTemplateColumn>
            <DataGridTemplateColumn.Header>
                <TextBlock Text="{Binding DataContext.HeaderNameText, RelativeSource={RelativeSource AncestorType={x:Type DataGrid}}}" />
            </DataGridTemplateColumn.Header>
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <StackPanel>
                        <TextBlock Text="{Binding}" />
                    </StackPanel>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
        </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>

and the DataContext of the DataGrid is set like so :

Data data = new Data();
data.HeaderNameText = "Header2";
data.Items = new List<string>() { "Item1", "Item2" };
DataContext = data;

the Data class structure is as follow :

public class Data
{
    public string HeaderNameText { get; set; }
    public List<string> Items { get; set; }
}

my question is how to Bind the DataGrid ItemSource to multiple columns data :

List<Data> data=new List<Data>();

i am expecting to get a column for every data element in the above list, so how to achieve that?

Given approach defines just one column

<DataGrid>
    <DataGrid.Columns>
        <DataGridTemplateColumn ...>
    </DataGrid.Columns>
</DataGrid>

For multiple columns you'll have to define it multiple times

<DataGrid>
    <DataGrid.Columns>
        <DataGridTemplateColumn ...>
        <DataGridTemplateColumn ...>
        <DataGridTemplateColumn ...>
    </DataGrid.Columns>
</DataGrid>

If you define columns like this

public class Data
{
    public string[] HeaderNameText { get; set; } // array, list, etc.
    public List<string> Items { get; set; }
}

then binding will be something like

{Binding DataContext.HeaderNameText[0] ...}
{Binding DataContext.HeaderNameText[1] ...}

etc.
