参考代码

 

Dim dlg As New OpenFileDialog
dlg.Filter = "Excel文件|*.xls;*.xlsx"
If dlg.ShowDialog =DialogResult.OK Then
    Dim t As Table = Tables("表B")
    Dim cs As String() = {"第一列", "第二列", "第三列"}
    t.StopRedraw()
    Dim Book As New XLS.Book(dlg.FileName)
    Dim Sheet As XLS.Sheet = Book.Sheets(0)
    For n As Integer = 1 To Sheet.Rows.Count -1
        Dim r As DataRow = t.DataTable.Find("第一列 = '" & sheet(n, 0).text & "'")
        If r Is Nothing Then r = t.DataTable.AddNew()
        For i As Integer = 0 To sheet.Cols.Count -1
            Dim cname As String = sheet(0, i).text
            If array.indexof(cs,cname) >= 0 Then
                r(cname) = sheet(n, i).Text
            End If
        Next
    Next
    t.ResumeRedraw()
End If

看懂3楼代码，如果不会做，上传具体实例说明你的问题。

dlg.Filter = "Excel文件|*.xls;*.xlsx"
If dlg.ShowDialog =DialogResult.OK Then
    Dim t As Table = Tables("海报印刷投递表")
    Dim cs As String() = {"门店", "订单号", "印刷量","投递量"}
    t.StopRedraw()
    Dim Book As New XLS.Book(dlg.FileName) '定义一个Excel工作簿
    Dim Sheet As XLS.Sheet = Book.Sheets(0) '引用工作簿的第一个工作表
    For n As Integer = 2 To Sheet.Rows.Count -1
