Error ว่า Column 'PersonCode' does not belong to table ช่วยดู code ให้หน่อยครับ

private void CreateTable()
    {
        DataTable dt = new DataTable();
        string[] Test1 = Session["PersonCode"].ToString().Split('|');
        string[] Test2 = Session["TranRequestID"].ToString().Split('|');
        string[] Test3 = Session["Name"].ToString().Split('|');
        string[] Test4 = Session["CourseName"].ToString().Split('|');
        string[] Test5 = Session["CompanyName"].ToString().Split('|');
        string[] Test6 = Session["ProductName"].ToString().Split('|');
        string[] Test7 = Session["Shift"].ToString().Split('|');
        string[] Test8 = Session["Cell"].ToString().Split('|');
        string[] Test9 = Session["xTrainStatus"].ToString().Split('|');
        int recordnum = Test1.Length;

        for (int j = 0; j < recordnum - 1; j++)
        {

            DataRow dr = dt.NewRow();
            dr["PersonCode"] = Test1[j].ToString();
            dr["TranRequestID"] = Test2[j].ToString();
            dr["Name"] = Test3[j].ToString();
            dr["CourseName"] = Test4[j].ToString();
            dr["CompanyName"] = Test5[j].ToString();
            dr["ProductName"] = Test6[j].ToString();
            dr["Shift"] = Test7[j].ToString();
            dr["Cell"] = Test8[j].ToString();
            dr["xTrainStatus"] = Test9[j].ToString();
            dt.Rows.Add(dr);

        }

        GridView1.DataSource = dt.DefaultView;
        GridView1.DataBind();

    }
