尝试启动时指示失败 该如何解决？
错误：AttributeError：'_tkinter.tkapp'对象没有属性'root'； app = Trgbhtml（）; self.lblR = TLabel（self，text =“ R =”，font = f）

错误告诉您您使用with t as(
select row_number() over (partition by m order by d) as rn
,(row_number() over (partition by m order by d)-1) / 5 as gn
,*
from @t
where m = 1
)
select *
,case when p > r
then r + (sum(case when p < r then r else 0 end) over (partition by gn) / sum(case when p > r then 1 else 0 end) over (partition by gn))
else case when p = r
then r
else 0
end
end as r_adj
from t;
作为with t as(
select row_number() over (partition by m order by d) as rn
,(row_number() over (partition by m order by d)-1) / 10 as gn
,(row_number() over (partition by m order by d)+4) / 10 as gn2
,*
from @t
where m = 1
)
,r1 as(
select *
,case when p > r
then r + (sum(case when p < r then r - p else 0 end) over (partition by gn) / sum(case when p > r then 1. else 0. end) over (partition by gn))
else case when p = r
then r
else 0
end
end as r_adj
from t
)
select d
,m
,p
,r
,case when p > r_adj
then r_adj + (sum(case when p < r_adj then r_adj - p else 0 end) over (partition by gn2) / sum(case when p > r_adj then 1. else 0. end) over (partition by gn2))
else case when p = r_adj
then r_adj
else r_adj - (r_adj - p)
end
end as r_new
from r1
order by rn

的父级，但是self不是小部件。您只能将小部件用作其他小部件的父代。
