DataGridView二维表头与合并单元格

DataGridView 二维表头与合并单元格 1、在项目中添加“组件类”。 2、所引用的命名空间如下： using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Collections; using System.ComponentModel; using System.Windows.Forms; using System.Drawing; using System.Drawing.Design; using System.Diagnostics; 3、DataGridView 二维表头与合并单元格类，继承 DataGridView 类 public partial class HeaderUnitView : DataGridView { private TreeView[] _columnTreeView; private ArrayList _columnList = new ArrayList(); private int _cellHeight = 17; public int CellHeight { get { return _cellHeight; } set { _cellHeight = value; } } private int _columnDeep = 1; private bool HscrollRefresh = false; ///
