我写了一个C#程序来创建一个excel电子表格.工作表有多个列.我想格式化一列.
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,当格式化列正确时,它也格式化格式的其他列,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bug还是我错过了什么？
解决方法
你打开现有文件吗？在打开之前,它可能已经应用于其他列的格式.或者像阿斯坦这样的模板说.
清除所有的格式,以防万一如下：
ws.Cells["A:D"].Style.Numberformat.Format = null; ws.Cells["B:B"].Style.Numberformat.Format = "0.00";

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[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();
}
