--  导入excel中所有的sheet内容
就是如果这个excel中包括了多个sheet，每个sheet的列名格式都是一样的。
怎么样一次导入？

循环逐个sheet导入

Dim Book As New XLS.Book("c:\\test\\订单.xls")
Tables("订单").StopRedraw()
for each Sheet as XLS.Sheet in Book.Sheets
\'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 = {"编号","产品","客户","雇员","单价","折扣","数量","日期"}
\'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 r As Row = Tables("订单").AddNew()
    For m As Integer = 0 To nms.Length - 1
         r(nms(m)) = Sheet(n,m).Value
    Next
Next
next
Tables("订单").ResumeRedraw()

万一某个sheet是空表呢？这样不就认为格式不对。空表应该不算才行。

关闭项目，重新打开，重新测试。

测试时，去掉 Systemready = False

按照你说的做好像也没用，请再帮忙排查一下。

加上红色代码

catch ex As exception

    msgbox(ex.message)

finally
