无法在C#中使用epplus从dataTable中导出excel文件

using OfficeOpenXml;

using System.Data;
using System.IO;

public class ExcelExporter
{
    public static void ExportToExcel(DataTable dataTable, string filePath)
    {
        using (ExcelPackage package = new ExcelPackage())
        {
            ExcelWorksheet worksheet = package.Workbook.Worksheets.Add("Sheet1");

            // 将DataTable的列名写入Excel第一行
            for (int i = 0; i < dataTable.Columns.Count; i++)
            {
                worksheet.Cells[1, i + 1].Value = dataTable.Columns[i].ColumnName;
            }

            // 将DataTable的数据写入Excel
            for (int row = 0; row < dataTable.Rows.Count; row++)
            {
                for (int col = 0; col < dataTable.Columns.Count; col++)
                {
                    worksheet.Cells[row + 2, col + 1].Value = dataTable.Rows[row][col];
                }
            }

            // 保存Excel文件
            FileInfo file = new FileInfo(filePath);
            package.SaveAs(file);
        }
    }
}
