UWP Community Toolkit, Datagrid control : how to align cell content on the right

Question

I have a numerical column in a Datagrid that I want your content to be right aligned. I I read the documentation, chiefly Customizable templates and styling for Cells, Rows and headers where I finished with this code to get the cell content aligned to the right:

<controls:DataGrid.CellStyle>
    <Style TargetType="controls:DataGridCell">
        <Style.Setters>
            <Setter Property="HorizontalAlignment" Value="Right"/>
        </Style.Setters>
    </Style>
</controls:DataGrid.CellStyle>

As you might expect, this code actually does what I want, but with all the cells. I want only the numerical column to have that property, and only it, but I have been unable to achieve that.

What am I doing wrong?
