设计MVVM中的动态行标题，列标题和内容

Question

我想要一个项目源，它提供了对MVVM模式中列标题，行标题及其内容的绑定。我试过DataTable，但是，我不知道如何填充行标题。在添加DataRow期间可以填充rowheader？

DataRow dr = new DataRow(); 
dr.ItemArray = current.Split(new char[] { '\t' }); 
// add row header? 

请帮忙。

这是你想要的吗？

XAML代码：

<Grid> 
    <DataGrid Name="SimpleDataGrid" AutoGenerateColumns="True" ItemsSource="{Binding}" /> 
</Grid> 

创建新的数据行：

private void CreateNewDataRow() 
{ 
    // Use the MakeTable function below to create a new table. 
    DataTable table; 
    table = MakeNamesTable(); 

    // Once a table has been created, use the 
    // NewRow to create a DataRow. 
    DataRow row; 
    row = table.NewRow(); 

    // Then add the new row to the collection. 
    row["fName"] = "John"; 
    row["lName"] = "Smith"; 
    table.Rows.Add(row); 

    foreach (DataColumn column in table.Columns) 
    { 
     Console.WriteLine(column.ColumnName); 
    } 

    SimpleDataGrid.DataContext = table; 
} 

创建新列：

private DataTable MakeNamesTable() 
{ 
    // Create a new DataTable titled 'Names.' 
    DataTable namesTable = new DataTable("Names"); 

    // Add three column objects to the table. 
    DataColumn idColumn = new DataColumn(); 
    idColumn.DataType = System.Type.GetType("System.Int32"); 
    idColumn.ColumnName = "id"; 
    idColumn.AutoIncrement = true; 
    namesTable.Columns.Add(idColumn); 

    DataColumn fNameColumn = new DataColumn(); 
    fNameColumn.DataType = System.Type.GetType("System.String"); 
    fNameColumn.ColumnName = "Fname"; 
    fNameColumn.DefaultValue = "Fname"; 
    namesTable.Columns.Add(fNameColumn); 

    DataColumn lNameColumn = new DataColumn(); 
    lNameColumn.DataType = System.Type.GetType("System.String"); 
    lNameColumn.ColumnName = "LName"; 
    namesTable.Columns.Add(lNameColumn); 

    // Create an array for DataColumn objects. 
    DataColumn[] keys = new DataColumn[1]; 
    keys[0] = idColumn; 
    namesTable.PrimaryKey = keys; 

    // Return the new DataTable. 
    return namesTable; 
} 

调用CreatingNewDataRow（）：

public MainWindow() 
{ 
    InitializeComponent(); 

    CreateNewDataRow(); 
}
