DataTable二次封装排序(Sort)

 private DataTable DtSortA(DataTable Dt, string column)
 {
            DataTable dtNew = Dt.Clone();
            dtNew.Columns[column].DataType = typeof(DateTime);
            foreach (DataRow s in Dt.Rows)

                dtNew.ImportRow(s);//导入旧数据
            }
            dtNew.DefaultView.Sort = column + " desc";
            dtNew = dtNew.DefaultView.ToTable();
