dataGridView添加列行

//每一列必须设置CellTemplate
            //第一列
             dataGridView1.Columns.Add(new DataGridViewColumn() {Name="name", HeaderText = "姓名", Width = 100,CellTemplate = new DataGridViewTextBoxCell(), MinimumWidth=100});


            //第二列
            DataGridViewColumn ageColumn = new DataGridViewColumn()
            {
                Name = "age",
                HeaderText = "年龄",
                Width = 100,
                CellTemplate = new DataGridViewTextBoxCell()
            };
            //设置文本对齐方式
            ageColumn.DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter;
            //设置该列背景颜色
            ageColumn.DefaultCellStyle.BackColor = Color.Red;
            dataGridView1.Columns.Add(ageColumn);

            //添加行
            for (int i = 0; i < 10; i++)
            {
                dataGridView1.Rows.Add(new string[] { "宝宝" + i, "宝年" + i });
