更多详细操作，请见：https://www.cnblogs.com/karkash/p/16310441.html

01]建立缓存表

procedure TForm1.FormCreate(Sender: TObject);
begin
 FDMemTable1.Close();
FDMemTable1.FieldDefs.Clear();
//定义表结构
FDMemTable1.FieldDefs.Add('ID', ftInteger, 0, True);
FDMemTable1.FieldDefs.Add('Name', ftString, 20, false);
FDMemTable1.CreateDataSet();

//添加数据
FDMemTable1.AppendRecord([101, 'aaa']);
FDMemTable1.AppendRecord([102, 'bbb']);
FDMemTable1.AppendRecord([103, 'ccc']);
FDMemTable1.AppendRecord([1201, 'ddaaa']);
FDMemTable1.AppendRecord([1202, 'ddbbb']);
FDMemTable1.AppendRecord([1203, 'dsccc']);
end;

02]获得指定  单元格 的值

procedure TForm1.Button1Click(Sender: TObject);
var
  i: Integer;
begin
  for i := 0 to FDMemTable1.SourceView.Rows.Count - 1 do   begin
    Caption := FDMemTable1.SourceView.Rows.ItemsI[i].GetData(0);
                                               //i 为行，  0 为列
  end;
end; 

  //4行1列的值。
 FDMemTable1.Data.DataView.Rows.ItemsI[4].ValueI[1]
 FDMemTable1.Table.Rows[4].ValueI[1]
