select ข้อมูล reportList แสดงใน datagrid ครับ...................

 DataTable dt = new DataTable("UNF");
                dt.Columns.Add("U");    
                dt.Columns.Add("A");

for แต่ละ line
{
  for เพื่อแยกข้อความออกมา
 {
    datarow r = dt.newrow;
   r("U")= ไอ้ตัวที่แยกมาน่านแหละ
   r("A")= ไอ้ตัวที่แยกมาน่านแหละ อีกอัน
   dt.Rows.Add(dr);
