你需要使用模板？如果没有使用普通的 标题 属性：

Do you need to use a template? If not use the normal Header property:

string colProperty = "Name";

DataGridTextColumn col = new DataGridTextColumn();
col.Binding = new Binding(colProperty);
var spHeader = new StackPanel() { Orientation = Orientation.Horizontal };
spHeader.Children.Add(new TextBlock(new Run(colProperty)));
var button = new Button();
button.Click += Button_Filter_Click;
button.Content = "Filter";
spHeader.Children.Add(button);
col.Header = spHeader;

dataGrid.Columns.Add(col);
