1、是不是你导入的数据都已经有了?
2、代码
Dim dlg As new OpenFileDialog
If dlg.ShowDialog = DialogResult.OK Then
Dim Book As New XLS.Book(dlg.FileName)
Dim Sheet As XLS.Sheet = Book.Sheets(0)
Tables("A110信息登记_明细").StopRedraw()
'注意以下数组中列名称的顺序,必须和Excel表中的列顺序一致
Dim nms() As String = {"流水号","报警时间","报警电话","报警人","报警类别","辖区","事发地点","报警内容"}
'注意下面的循环变量从1开始,而不是从0开始,因为Excel表的第一行是标题
For n As Integer = 1 To Sheet.Rows.Count -1
Dim bh As String = sheet(n,0).Text '取得流水号
If DataTables("A110信息登记_明细").Find("流水号= '" & bh & "'") Is Nothing Then
Dim r As Row = Tables("窗口1_table1").AddNew()
For m As Integer = 0 To nms.Length - 1
If Sheet(n,m).Text.Trim <> "" Then
r(nms(m)) = Sheet(n,m).Text.Trim
End If
Next
End If
Next
Tables("A110信息登记_明细").ResumeRedraw()
End If
