    {
        public Form1()

            // 创建一个DataGridView控件
            DataGridView dataGridView1 = new DataGridView();

            // 添加列
            dataGridView1.Columns.Add("Column1", "Column 1");
            dataGridView1.Columns.Add("Column2", "Column 2");

            DataGridViewColumn disableColumn = dataGridView1.Columns["Column2"];

            // 绑定CellEnter事件

            if (currentColumn.Name == "Column2")
