IronXL 與 Epplus 的比較

WorkBook workbook = WorkBook.Create(ExcelFileFormat.XLSX);

Dim workbook As WorkBook = WorkBook.Create(ExcelFileFormat.XLSX)

var sheet = workbook.CreateWorkSheet
```(2020年度預算);

在以上代碼片段中，工作表被表示為 "Sheet"，您可以用它設置單元格值並做幾乎所有Excel可以做的事情。您也可以將您的Excel文件編碼為只讀文件並執行刪除操作。 您還可以像Excel一樣鏈接您的工作表。

讓我澄清一下工作簿和工作表之間的區別，以防您不確定。

工作表包含在工作簿中。這意味著您可以在一個工作簿中放入任意多的工作表。我會在稍後的文章中解釋如何做到這一點。工作表由行和列構成。行和列的交集稱為單元格，這是您在Excel中將要互動的對象。

## 使用 Epplus Software AB 建立 Excel 檔案

EPPlus 可以用來建立 Excel 檔案並執行操作，例如建立樞紐分析表、樞紐範圍，甚至是條件格式化和字體變更。話不多說，以下是將普通的 DataTable 轉換為 XLSX Excel 檔案並發送給使用者下載的完整源代碼：

```cs
