Make the fonts bigger

Question

Hi experts, I would like to make the fonts bigger for the following codes, when the time is being retrieve out.

Thanks in advanced!

//generate time column from database

        SQL row = new SQL();

        DataTable lambo = row.schooltimeId();

        DataRow[] dr = new DataRow[lambo.Rows.Count];

        for (int i = 0; i < lambo.Rows.Count; i++)

        {

            dr[i] = table.NewRow();

            dr[i][keys[0]] = lambo.Rows[i][0] + ConfigurationSettings.AppSettings["DASH"] + lambo.Rows[i][1];

            table.Rows.Add(dr[i]);

        }
