用EPPLUS Excel Library格式化一列

Question

我寫了一個C＃程序來創建一個excel電子表格。該表有多個列。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(); 

的問題是，雖然它的格式化列正確的，它也格式化其他列的格式，而不僅僅是我指定的列。 我也試過：

ws.Column(1).Style.Numberformat.Format = "0.00"; 

這是一個錯誤還是我錯過了什麼？

Answer 1

你打開一個現有的文件？它可能有一種格式在打開之前已經應用到其他列。或者像astian這樣的模板說。

清除所有格式，以防萬一是這樣的：在EPPlus 4.0.3

ws.Cells["A:D"].Style.Numberformat.Format = null; 
ws.Cells["B:B"].Style.Numberformat.Format = "0.00";
