How to style Excel cell using Open XML - asp.net

Question

I have a requirement for export data to excel using open Xml plug in. And I want to style excel head boarder colour. I tried different method to achieve my requirement. Its done, But I couldn't not style particular cells (or columns). I have to add boarder and background to my excel cell.
My Code as following
public ActionResult exxx()
{
MemoryStream ms = new MemoryStream();
SpreadsheetDocument xl = SpreadsheetDocument.Create(ms, SpreadsheetDocumentType.Workbook);
WorkbookPart wbp = xl.AddWorkbookPart();
WorksheetPart wsp = wbp.AddNewPart<WorksheetPart>();
Workbook wb = new Workbook();
FileVersion fv = new FileVersion();
fv.ApplicationName = "Microsoft Office Excel";
Worksheet ws = new Worksheet();
//First cell
SheetData sd = new SheetData();
Row r1 = new Row() { RowIndex = (UInt32Value)1u };
Cell c1 = new Cell();
c1.DataType = CellValues.String;
c1.CellValue = new CellValue("some value");
r1.Append(c1);
// Second cell
Cell c2 = new Cell();
c2.CellReference = "C1";
c2.DataType = CellValues.String;
c2.CellValue = new CellValue("other value");
r1.Append(c2);
sd.Append(r1);
//third cell
Row r2 = new Row() { RowIndex = (UInt32Value)2u };
Cell c3 = new Cell();
c3.DataType = CellValues.String;
c3.CellValue = new CellValue("some string");
Cell c4 = new Cell();
c4.DataType = CellValues.String;
c4.CellValue = new CellValue("some car");
r2.Append(c3);
r2.Append(c4);
sd.Append(r2);
ws.Append(sd);
wsp.Worksheet = ws;
wsp.Worksheet.Save();
Sheets sheets = new Sheets();
Sheet sheet = new Sheet();
sheet.Name = "first sheet";
sheet.SheetId = 1;
sheet.Id = wbp.GetIdOfPart(wsp);
sheets.Append(sheet);
wb.Append(fv);
wb.Append(sheets);
xl.WorkbookPart.Workbook = wb;
xl.WorkbookPart.Workbook.Save();
xl.Close();
string fileName = "getdata.xlsx";
Response.Clear();
byte[] dt = ms.ToArray();
Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.AddHeader("Content-Disposition", string.Format("attachment; filename={0}", fileName));
Response.BinaryWrite(dt);
Response.End();
return File(dt, "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", "getdata.xlsx");
}
My expected result:

You need to create the style part and reference it by Cell c1 = new Cell() { StyleIndex = (UInt32Value)1U };.
Check
public ActionResult CreateExcel()
{
MemoryStream ms = new MemoryStream();
SpreadsheetDocument xl = SpreadsheetDocument.Create(ms, SpreadsheetDocumentType.Workbook);
WorkbookPart wbp = xl.AddWorkbookPart();
WorkbookStylesPart workbookStylesPart1 = wbp.AddNewPart<WorkbookStylesPart>("rId3");
GenerateWorkbookStylesPart1Content(workbookStylesPart1);
WorksheetPart wsp = wbp.AddNewPart<WorksheetPart>();
Workbook wb = new Workbook();
FileVersion fv = new FileVersion();
fv.ApplicationName = "Microsoft Office Excel";
Worksheet ws = new Worksheet();
//First cell
SheetData sd = new SheetData();
Row r1 = new Row() { RowIndex = (UInt32Value)1u };
Cell c1 = new Cell() { StyleIndex = (UInt32Value)1U };
c1.DataType = CellValues.String;
c1.CellValue = new CellValue("some value");
r1.Append(c1);
// Second cell
Cell c2 = new Cell() { StyleIndex = (UInt32Value)1U };
c2.CellReference = "C1";
c2.DataType = CellValues.String;
c2.CellValue = new CellValue("other value");
r1.Append(c2);
sd.Append(r1);
//third cell
Row r2 = new Row() { RowIndex = (UInt32Value)2u };
Cell c3 = new Cell();
c3.DataType = CellValues.String;
c3.CellValue = new CellValue("some string");
Cell c4 = new Cell();
c4.DataType = CellValues.String;
c4.CellValue = new CellValue("some car");
r2.Append(c3);
r2.Append(c4);
sd.Append(r2);
ws.Append(sd);
wsp.Worksheet = ws;
wsp.Worksheet.Save();
Sheets sheets = new Sheets();
Sheet sheet = new Sheet();
sheet.Name = "first sheet";
sheet.SheetId = 1;
sheet.Id = wbp.GetIdOfPart(wsp);
sheets.Append(sheet);
wb.Append(fv);
wb.Append(sheets);
xl.WorkbookPart.Workbook = wb;
xl.WorkbookPart.Workbook.Save();
xl.Close();
string fileName = "getdata.xlsx";
Response.Clear();
byte[] dt = ms.ToArray();
//Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
//Response.AddHeader("Content-Disposition", string.Format("attachment; filename={0}", fileName));
//Response.BinaryWrite(dt);
//Response.End();
return File(dt, "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", "getdata.xlsx");
