开发人员可以从数据表通过调用他们的工作表导入数据表Cells采集方法。有许多重载版本导入数据表方法，但典型的重载采用以下参数：数据表 , 代表数据表需要导入内容的对象
- 是否显示字段名称指定是否应将 DataTable 的列名称作为第一行导入工作表
- 开始 Cell 表示从中导入 DataTable 内容的起始单元格的名称（即“A1”）
//Instantiating a Workbook object
Workbook workbook = new Workbook();
//Adding a new worksheet to the Workbook object
int i = workbook.Worksheets.Add();
//Obtaining the reference of the newly added worksheet by passing its sheet index
Worksheet worksheet = workbook.Worksheets[i];
//Instantiating a "Products" DataTable object
DataTable dataTable = new DataTable("Products");
//Adding columns to the DataTable object
dataTable.Columns.Add("Product ID", typeof(Int32));
dataTable.Columns.Add("Product Name", typeof(string));
dataTable.Columns.Add("Units In Stock", typeof(Int32));
//Creating an empty row in the DataTable object
DataRow dr = dataTable.NewRow();
//Adding data to the row
dr[0]= 1;
dr[1]= "Aniseed Syrup";
dr[2]= 15;
//Adding filled row to the DataTable object
dataTable.Rows.Add(dr);
//Creating another empty row in the DataTable object
dr = dataTable.NewRow();
//Adding data to the row
dr[0]= 2;
dr[1]= "Boston Crab Meat";
dr[2]= 123;
//Adding filled row to the DataTable object
dataTable.Rows.Add(dr);
//Importing the contents of DataTable to the worksheet starting from "A1" cell,
//where true specifies that the column names of the DataTable would be added to
//the worksheet as a header row
worksheet.Cells.ImportDataTable(dataTable, true, "A1");
workbook.Save("Import From Data Table.xls");
