实现：在导入发票后，对发票分录表格根据开票日期进行排序

脚本：

   BizAccountBill_Edit_Open.invoiceClose = function(result) {
         _public.super_invoiceClose(result);
         waf("#ticketEntries").wafGrid('reloadGrid');
         waf("#ticketEntries").wafGrid('sortGrid','billingDate',"asc");
    };
    waf.extend(_public, {
        super_invoiceClose:_self.invoiceClose
    })
