I wrote a C# program to create an excel spreadsheet. The sheet has multiple columns. I want to format ONE of the columns.
aFile = new FileInfo(excelDocName); // excelDocName is a string
ExcelPackage pck = new ExcelPackage(aFile);
var ws = pck.Workbook.Worksheets.Add("Content");
ws.View.ShowGridLines = true;
ws.Cells["B:B"].Style.Numberformat.Format = "0.00";
ws.Cells[1, 1].Value = "AA";
ws.Cells[1, 2].Value = "BB";
ws.Cells[1, 3].Value = "CC";
ws.Cells[1, 4].Value = "DD";
for (int row = 2; row <= 10; ++row)
for (int col = 1; col <= 4; ++col)
{
ws.Cells[row, col].Value = row * col;
}
ws.Row(1).Style.Font.Bold = true;
pck.Save();
The problem is, while it's formatting the column correct, it's also formatting other columns with the format and not just the column I specified. I also tried:
ws.Column(1).Style.Numberformat.Format = "0.00";
Is this a bug or am I missing something?
Are you opening an existing file? It may have a format already applied to the other columns prior to you opening it. Or a template like astian said.
Clear all the formatting just in case like this:
ws.Cells["A:D"].Style.Numberformat.Format = null;
ws.Cells["B:B"].Style.Numberformat.Format = "0.00";

{
ws.Cells[row, col].Value = row*col;
}
ws.Row(1).Style.Font.Bold = true;
pck.Save();
}
