        dataGridView.Columns.Add("StartTime", "Start Time");

        // 添加示例数据
        dataGridView.Rows.Add(1, "Task 1", DateTime.Now);
        dataGridView.Rows.Add(2, "Task 2", DateTime.Now.AddDays(1));

        // 设置日期时间列的格式
        dataGridView.Columns["StartTime"].DefaultCellStyle.Format = "yyyy-MM-dd HH:mm:ss";

        this.Controls.Add(dataGridView);
    }

    [STAThread]
    static void Main()
