New Post: Excel Sheet Spacing inside a Merged Rows

I have created worksheet where it contains a merged column with many values each value should have some fixed space.

Please let me know to fix a space between each values in a merged column

 foreach (var r1 in Round1)
            {
                row++;

                Worksheet1.Cell(row, 3).Value = r1.Program;
                Worksheet1.Range(row, 3, row, 4).Merge().AddToNamed("Titles");
                Worksheet1.Cell(row, 5).Value = r1.RobotNo + " " + r1.Description + " " + r1.PaintNo + " " + r1.PartNo + " " + "EVERY STEM";
                row++;
                Worksheet1.Cell(row, 3).Value = "No of pair";
                Worksheet1.Cell(row, 4).Value = r1.NoofPairs;
                row++;
                Worksheet1.Cell(row, 3).Value = "No of Racks";
                Worksheet1.Cell(row, 4).Value = r1.NoofRacks;
                Worksheet1.Cell(row, 2).Value = r1.NoofRacks;
                row++;
                Worksheet1.Cell(row, 2).Value = r1.Stem;
                Worksheet1.Range(row, 3, row, 12).Merge().AddToNamed("Titles");
                if (r1.Stem == "1")
                {
                    Worksheet1.Cell(row, 3).Value = "BATCH FLAG";
                    Worksheet1.Row(row).Style.Fill.BackgroundColor = XLColor.FromArgb(0xCCFFCCF);
                }
                else if (r1.Stem == "0")
                {
                }
                else
                {
                    Worksheet1.Row(row).Style.Fill.BackgroundColor = XLColor.FromArgb(0xCCFFCCF);
                    Worksheet1.Cell(row, 3).Value = "BATCH FLAG AND " + r1.StemBuffer + " EMPTY STEM";
                }
            }
            row++;

            Worksheet1.Cell(row, 2).Value = TStem1;

            row = 1;

In the above code:
Worksheet1.Cell(row, 5).Value = r1.RobotNo + " " + r1.Description + " " + r1.PaintNo + " " + r1.PartNo + " " + "EVERY STEM";

contains a many values in merge column i need to fix a more space between each value
