What I have tried:

Here is my data table code:

private void button1_Click(object sender, EventArgs e)
{
Excel.Application xlApp;
Excel.Workbook xlWorkBook;
Excel.Worksheet xlWorkSheet;
object misValue = System.Reflection.Missing.Value;
Excel.Range chartRange;

xlApp = new Excel.Application();
xlWorkBook = xlApp.Workbooks.Add(misValue);
xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);

xlWorkSheet.Cells[2, 1] = "Retailer";

xlWorkSheet.Cells[2, 2] = "Brand";
xlWorkSheet.Cells[2, 3] = "2019_WK1";

xlWorkSheet.Cells[2, 4] = "2019_WK2";

xlWorkSheet.Cells[2, 5] = "2019_WK3";

xlWorkSheet.Cells[3, 1] = "LuLu";
xlWorkSheet.Cells[3, 2] = "Perisil";
xlWorkSheet.Cells[3, 3] = "25";
xlWorkSheet.Cells[3, 4] = "26";
xlWorkSheet.Cells[3, 5] = "23";

xlWorkSheet.Cells[4, 1] = "Lulu";
xlWorkSheet.Cells[4, 2] = "Ariel";
xlWorkSheet.Cells[4, 3] = "26";

xlWorkSheet.Cells[5, 1] = "Danube";
xlWorkSheet.Cells[5, 2] = "Omo";
xlWorkSheet.Cells[5, 3] = "27";
xlWorkSheet.Cells[5, 4] = "28";
xlWorkSheet.Cells[5, 5] = "30";

xlWorkSheet.Cells[6, 1] = "Danube";
xlWorkSheet.Cells[6, 2] = "Tide";
xlWorkSheet.Cells[6, 3] = "24";
xlWorkSheet.Cells[6, 4] = "23";
xlWorkSheet.Cells[6, 5] = "29";

xlWorkBook.SaveAs("F:\\CTR_Data", Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
xlWorkBook.Close(true, misValue, misValue);

a1 to e1 would be five empty columns not rows. The easiest way would be to just put your data in the correct columns in the first place

Start by removing all those fixed row and column numbers and replace them by variables so you can add other rows at the required positions.

Solution 1

Try this before call xlWorkBook.SaveAs:

C#

Range line = (Range)xlWorkSheet.Rows[1];
for (int i = 0; i < 5; i++) line.Insert(XlInsertShiftDirection.xlShiftDown, false);

However, I suggest to experiment a little with EPPlus. Just for fun, who knows, maybe you'll love it :)

Basically, your app is remote controlling Excel, so anything you do on Excel can be done on remote. It is interesting because Excel can show you how your actions translate to code.
Excel have a feature: recording a macro.
When you record a macro, all your actions are translated to VBA code. After end of recording, just have to go to VBE (Alt+F11) to see the code generated.
Even if VBA, the generated code will be close enough to what you need to be useful.
