我编写了一个 C# 程序来创建 Excel 电子表格。该工作表有多个列。我想格式化其中一列。
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();
问题是,虽然它正确地格式化了该列,但它还使用该格式格式化其他列,而不仅仅是我指定的列。 我也试过:
ws.Column(1).Style.Numberformat.Format = "0.00";
这是一个错误还是我遗漏了什么?
最佳答案
您要打开现有文件吗?在您打开它之前,它的格式可能已经应用于其他列。或者像 astian 所说的模板。
清除所有格式以防万一:
ws.Cells["A:D"].Style.Numberformat.Format = null;
ws.Cells["B:B"].Style.Numberformat.Format = "0.00";
EPPlus 4.0.3 中的完整单元测试:

var excelDocName = @"c:\temp\temp.xlsx";
var aFile = new FileInfo(excelDocName); // excelDocName is a string
if (aFile.Exists)
aFile.Delete();
ExcelPackage pck = new ExcelPackage(aFile);
var ws = pck.Workbook.Worksheets.Add("Content");
ws.View.ShowGridLines = true;
ws.Cells["A:D"].Style.Numberformat.Format = null;
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();
}
