编辑DataGrid单元格并在WPF中将一些单元格相互绑定

Question

在DataGrid上我有列：Last counter，Current counter，Current kilos。我想要的是输入列的数据：Last counter，Current counter和Current kilos列将通过减去当前计数器得到它的数据来自（最后一个柜台）。我想直接在DataGrid上这样做。 有没有办法将列绑定到其他列以执行我在Xaml中要求的操作？

这是DataGrid的Xaml代码

<Grid>
    <DataGrid FrozenColumnCount="1" Name="grid1" AutoGenerateColumns="False" AlternationCount="2" ItemsSource="{Binding}"  Height="auto" Width="auto" Margin="0,163,0,10" 
        MinRowHeight="26" FontSize="18" Foreground="Black" Background="LightBlue"  >
        <DataGrid.Columns>
            <DataGridTextColumn Binding="{Binding cfname}"  Header="First name"/>
            <DataGridTextColumn Binding="{Binding cmname}"  Header="Middle name"/>
            <DataGridTextColumn Binding="{Binding clname}"  Header="Last name"/>
            <DataGridTextColumn Binding="{Binding address}" ClipboardContentBinding="{x:Null}" Header="Address"/>
            <DataGridTextColumn Binding="{Binding boxnumber}" ClipboardContentBinding="{x:Null}" Header="box number"/>
            <DataGridTextColumn Binding="{Binding discount}" ClipboardContentBinding="{x:Null}" Header="Discount"/>
            <DataGridTextColumn Binding="{Binding typeofsub}" ClipboardContentBinding="{x:Null}" Header="subscription type"/>
            <DataGridTextColumn Binding="{Binding ampere}" ClipboardContentBinding="{x:Null}" Header="subscription"/>
            <DataGridTextColumn Binding="{Binding required}" ClipboardContentBinding="{x:Null}" Header="Fee"/>
            <DataGridTextColumn Binding="{Binding lastkilos}" ClipboardContentBinding="{x:Null}" Header="Last counter"/>
            <DataGridTextColumn  ClipboardContentBinding="{x:Null}" Header="current counter"/>
            <DataGridCheckBoxColumn  ClipboardContentBinding="{x:Null}" Header="current kilos"/>
            <DataGridCheckBoxColumn  ClipboardContentBinding="{x:Null}" Header="price"/>
            <DataGridCheckBoxColumn  ClipboardContentBinding="{x:Null}" Header="Total cost"/>
        </DataGrid.Columns>

    </DataGrid>
