求教用NPOI读取excel到DataTable中时如何不让表头生成

Answer 1

/// <summary>读取excel
/// 默认第一行为标头
/// </summary>
/// <param name="strFileName">excel文档路径</param>
/// <returns></returns>
public static DataTable Import(string strFileName)
{
DataTable dt = new DataTable();

HSSFWorkbook hssfworkbook;
using (FileStream file = new FileStream(strFileName, FileMode.Open, FileAccess.Read))
{
hssfworkbook = new HSSFWorkbook(file);
}
HSSFSheet sheet = hssfworkbook.GetSheetAt(0);
System.Collections.IEnumerator rows = sheet.GetRowEnumerator();

HSSFRow headerRow = sheet.GetRow(0);
int cellCount = headerRow.LastCellNum;

for (int j = 0; j < cellCount; j++)
{
HSSFCell cell = headerRow.GetCell(j);
dt.Columns.Add(cell.ToString());
}

for (int i = (sheet.FirstRowNum + 1); i <= sheet.LastRowNum; i++)
{
HSSFRow row = sheet.GetRow(i);
DataRow dataRow = dt.NewRow();

for (int j = row.FirstCellNum; j < cellCount; j++)
{
if (row.GetCell(j) != null)
