主题：[求助]将三个表格某列进行合并筛选？

这个意思？

If e.DataCol.name = "乡镇" Then
    Dim count1 = DataTables("A表").getvalues("XJHZXM", "XZMC='" & e.DataRow("乡镇") & "'").count
    Dim count2 = DataTables("B表").getvalues("XJHZXM", "XZMC='" & e.DataRow("乡镇") & "'").count
    Dim count3 = DataTables("C表").getvalues("XJHZXM", "XZMC='" & e.DataRow("乡镇") & "'").count
    e.DataRow("XJHZSL") = count1+count2+count3
End If
