C# Winform表格DataGridView自定義列（文本列、ComboBox列）

例子：

DataGridView dv = this.dataGridView1;

//自定義普通文本列
DataGridViewTextBoxColumn dc3 = new DataGridViewTextBoxColumn();
            dc3.Name = "FMapName";
            dc3.DataPropertyName = "FMapName";
            dc3.HeaderText = "對應名稱";
            dc3.ReadOnly = true;
            dv.Columns.Add(dc3);

//自定義ComboBox列（整個列的每一行都有一個ComboBox控件）
DataGridViewComboBoxColumn dc2 = new DataGridViewComboBoxColumn();
            dc2.HeaderText = "對應代碼";
            dv.Columns.Add(dc2);  //注意要加上這句才能添加
