主题：同步加载子表，适不适合加载外部数据表

应该这样

beforeloadoutertable事件

Select Case e.DataTablename    

    Case "个人持证情况表","员工职称表","员工基础表"

        e.SelectString = "Select * From {" & e.DataTablename & "} Where [_Identify] Is Null"

End Select

afteropenproject事件

DataTables("员工基础表").loadfilter = "[部门] = '" & usbm & "'"

DataTables("员工基础表").load

"员工基础表"的afterload表事件:

e.DataTable.LoadChildren("个人持证情况表")

e.DataTable.LoadChildren("员工职称表")
