I use this package: ExcelPackage though I can't figure out how to set the background color for the cell. I tried to use this:
ws.Cells["A1"].Style.Fill.PatternType = OfficeOpenXml.Style.ExcelFillStyle.Solid;
But it shows that the properties are not found.
Sounds like I should use something similar to this:
worksheet.Cell(5, columnIndex + 1).Style = "background-color: red";
But I am not sure how it works and I couldn't find the tutorial for it. Please help.
