大牛们请问一下：WPF中DataGrid怎么样可以增加列并删除列，可以任意选中一列删除？

Question

//Datagridview添加列       
            DataGridViewTextBoxColumn acCode = new DataGridViewTextBoxColumn();
            acCode.Name = "acCode";
            acCode.DataPropertyName = "acCode";
            acCode.HeaderText = "A/C Code";
            dgvVouchers.Columns.Add(acCode);
 
 
 //Datagridview创建行
            //DataGridViewRow dr = new DataGridViewRow();        
            //dr.CreateCells(dgvVouchers);
            //添加的行作为第一行
            //dgvVouchers.Rows.Insert(0, dr);                   
            //添加的行作为最后一行
            //dgvVouchers.Rows.Add(dr_new);

DataTable嵌入DataGrid，DataTable可以通过Rows和Columns删除行和列
 private void AddData_Click(object sender, RoutedEventArgs e)
        {
            DataRow dr = dt.NewRow();
            for (int columIndex = 0; columIndex < dt.Columns.Count; columIndex++)
            {
                if (columIndex == 0)
                    dr[columIndex] = "第" + dt.Rows.Count.ToString() + "组";
                else
                    dr[columIndex] = "";
                //dr[columIndex] = dt.Rows.Count.ToString() + " - " + columIndex.ToString();
            }
            dt.Rows.Add(dr);
        }        int newColumnIndex = 5;
        //增加一列
        private void AddColumn_Click(object sender, RoutedEventArgs e)
        {
            dt.Columns.Add(new DataColumn("" + newColumnIndex++));
            for (int i = 0; i < dt.Rows.Count; i++)
            {
                if (i == 0)
                    dt.Rows[i][dt.Columns.Count - 1] = "A" + (newColumnIndex - 1).ToString();
                else
                    dt.Rows[i][dt.Columns.Count - 1] = "";
                //dt.Rows[i][dt.Columns.Count - 1] = i.ToString() + " - " + (newColumnIndex - 1).ToString();
            }
            dataGrid.ItemsSource = null;
            dataGrid.ItemsSource = dt.DefaultView;
        }        //删除一行
        private void DeleteData_Click(object sender, RoutedEventArgs e)
        {
            if (dt.Rows.Count > 2)
            {
                if (dataGrid.SelectedIndex != -1 && dataGrid.SelectedIndex != 0 && dataGrid.SelectedIndex != dt.Rows.Count)
                {
                    dt.Rows.RemoveAt(dataGrid.SelectedIndex);
                }
                else
                {
                    dt.Rows.RemoveAt(dt.Rows.Count - 1);
                }
            }
        }
