WPF 数据表格：点击按钮增删行，可读可写

以下是 WPF 代码实现：

XAML 代码：

<Window x:Class="WpfApp1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="450" Width="800">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>
            <RowDefinition Height="Auto"/>
        </Grid.RowDefinitions>
        <Button Grid.Row="0" Content="Add Row" Click="AddRow_Click"/>
        <Button Grid.Row="2" Content="Delete Last Row" Click="DeleteRow_Click"/>
        <DataGrid Grid.Row="1" Name="dataGrid" AutoGenerateColumns="False">
            <DataGrid.Columns>
                <DataGridTextColumn Header="光源1" Binding="{Binding LightSource}" />
                <DataGridTextColumn Header="电流" Binding="{Binding Current}" />
                <DataGridTextColumn Header="电压" Binding="{Binding Voltage}" />
                <DataGridTextColumn Header="泵异常温度值" Binding="{Binding PumpAbnormalTemperature}" />
                <DataGridTextColumn Header="泵温度值" Binding="{Binding PumpTemperature}" />
                <DataGridTextColumn Header="功率异常值" Binding="{Binding PowerAbnormalValue}" />
                <DataGridTextColumn Header="功率值" Binding="{Binding PowerValue}" />
                <DataGridCheckBoxColumn Header="开/关" Binding="{Binding IsOn}" />
                <DataGridTextColumn Header="标示图字段" Binding="{Binding Image}" />
            </DataGrid.Columns>
        </DataGrid>
    </Grid>
</Window>

            }
        }

        private bool _isOn;

        }

        private string _image;
        public string Image

                OnPropertyChanged(nameof(Image));
            }
        }

        public DataRow()
        {
            // 设置默认值
            LightSource = "光源1";
            Current = 0;
            Voltage = 0;
            PumpAbnormalTemperature = 0;
            PumpTemperature = 0;
            PowerAbnormalValue = 0;
            PowerValue = 0;
            IsOn = false;
            Image = "";
        }

        public event PropertyChangedEventHandler PropertyChanged;

        protected virtual void OnPropertyChanged(string propertyName)
        {
            PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
        }
    }
}

效果如下图所示：
