DataGridcontrols has all that functionality built-in. You can set the properties CanUserAddRowsto true to allow user to add rows.
DataGrid控件具有内置的所有功能。您可以将属性CanUserAddRows设置为 true 以允许用户添加行。
DataGridis editable by default, where each column has an edit control which lets you edit its value. By default the DataGridautomatically generates columns for every property in your Model, so you don't even have to define it's columns.
DataGrid默认情况下是可编辑的，其中每列都有一个编辑控件，可让您编辑其值。默认情况下，会DataGrid为Model 中的每个属性自动生成列，因此您甚至不必定义它的列。
Here are some good links with detailed examples you can look into:

Have a Xaml as below
有一个 Xaml 如下
<Window x:Class="DatGrid.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525"
xmlns:local="clr-namespace:DatGrid">
<Window.DataContext>
<local:ViewModel/>
</Window.DataContext>
<StackPanel/>
<DataGrid ItemsSource="{Binding Path=Values}"></DataGrid>
</StackPanel>
</Window>
In the ViewModel is very simple some thing like below
在 ViewModel 中非常简单，如下所示
class ViewModel
{
public ObservableCollection<Example> Values
{
get;
set;
}
}
public class Example
{
public string A
{
get;
set;
}
public string B
{
get;
set;
}
}
In the view you can always see a empty row you can just click and type something and press enter it'll get updated to the ViewModel
在视图中，您始终可以看到一个空行，您只需单击并输入内容并按 Enter 键它就会更新到 ViewModel
