excel报表开发点滴

这几天公司有个报表开发需求，UI要求也相当高，讨论决定使用excel模版来做报表需求。

报表开发主要使用宏，后端是JAVA调用POI进行隐藏sheet的数据填充，最后执行宏绘制报表。

宏如下：

Sub auto_Open()
    Sheets("i18n").Select
    v = Range("B2").Value
    If v = 0 Then
        TravellerReprot
        Sheets("i18n").Select
        Range("B2").Value = 1
        
        Sheets("Traveller Anlysis Report").Select
        ActiveWorkbook.Save
    End If
    Sheets("Traveller Anlysis Report").Select
End Sub

特别注意的是注释那段，当关闭excel后会报告excel格式错误问题，但手动操作的没问题，非常怪异，特此标记一下。

VBA代码可以进一步进行优化，不过在那里面写真的是没eclipse方便...
另外经常写到循环或者判断的时候，打进去的代码居然是JAVA代码，悲催啊...
丫的，突然想起来这货不是JAVA啊~~~
