在css样式里面加上 white-space: pre-line; 就能识别后台string数据中的\n，将其换行
后台请求：
private object GetGridList(Pagination pagination, string keyword)
{
var list = xiangmuapp.GetList(pagination, keyword);
var listdetail = xiangmudetailapp.GetList(pagination, keyword);
foreach (var item in list)
{
var dataItemList = listdetail.FindAll(t => t.zhuid.Equals(item.zhuid));
