 2         /// 导入Excel文件按钮
 3         /// </summary>
 4         /// <param name="sender"></param>
 5         /// <param name="e"></param>
 6         private void InputExcelFile_Click(object sender, RoutedEventArgs e)
 7         {
 8             //将数据绑定到datagird控件中
 9             DataGridSheet.ItemsSource = readbynpoi.InputWorkbookFromExcel(GetExcelFilePath());
10             DataGridSheet.HeadersVisibility = DataGridHeadersVisibility.Row;
11             DataGridSheet.RowHeaderWidth = 30;
12             //LoadingRow事件
13             DataGridSheet.LoadingRow += DataGridSheet_LoadingRow;
14         }

16         private void DataGridSheet_LoadingRow(object sender, DataGridRowEventArgs e)
17         {
