可以只导出datatable列的一部分值吗？

DataRow[] filteredRows = dataTable.Select("姓名 = '张三'");

DataTable newTable = dataTable.DefaultView.ToTable(false, "姓名", "年龄");

using OfficeOpenXml;

using (ExcelPackage package = new ExcelPackage())
{
    ExcelWorksheet worksheet = package.Workbook.Worksheets.Add("Sheet1");

    // 写入列标题
    for (int col = 0; col < newTable.Columns.Count; col++)
    {
        worksheet.Cells[1, col + 1].Value = newTable.Columns[col].ColumnName;
    }

    // 写入数据
    for (int row = 0; row < newTable.Rows.Count; row++)
    {
        for (int col = 0; col < newTable.Columns.Count; col++)
        {
            worksheet.Cells[row + 2, col + 1].Value = newTable.Rows[row][col];
        }
    }

    // 保存Excel文件
    package.SaveAs(new FileInfo("export.xlsx"));
}
