winform中DataGirdView添加行号，根据某列的值改变颜色提示，奇偶数变色
1，添加行号效果展示，根据某列的值改变颜色提示效果展示
2，界面UI设置
行标题单元格样式要与默认单元格样式设置一致。
3，添加RowPostPaint事件
//DataGridView所有单元格发生绘制的后的事件
private void dgv_data_RowPostPaint(object sender, DataGridViewRowPostPaintEventArgs e)
{
AutomaticStoreMotionDal.DataGridViewHelper.DgvRowPostPaint(this.dgv_data, e);
//日志类型为操作记录的红色展示
AutomaticStoreMotionDal.DataGridViewHelper.DgvRowStyleWithResult(this.dgv_data, "日志类型", "操作记录", Color.Red);
}

添加行号方式2：
//加载表格
for (int i = 0; i < torqueList.Count(); i++)
{
dgv_data.Rows.Add();
dgv_data.Rows[i].HeaderCell.Style.Alignment = DataGridViewContentAlignment.MiddleRight;
dgv_data.Rows[i].HeaderCell.Value = (i + 1).ToString();//这种方式添加行号特别慢，影响性能，不推荐使用
dgv_data.Rows[i].Cells[0].Value = torqueList[i];
dgv_data.Rows[i].Cells[1].Value = angleList[i];
