我试图格式化这样的数据，用于我需要编写的报告： （每列的行数不同） 每个城市必须显示郊区列表，并且然后列出他们拥有的车辆列表奥斯汀。

City Suburbs Vehicles 
    1 Austin Bastrop Ford 
    2   Hutto  Mazda 
    3   Lakeway Mercedes

    11   Eastwood  Ford 
    12   GreenlandHills 
    13   LakeParkEstates

这是源数据

declare @Test0 table(city nvarchar(10), [state] varchar(30)) 
    insert into @Test0 values ('Austin', 'Texas') 
    insert into @Test0 values ('Dallas', 'Texas') 

declare @Test1 table (city nvarchar(10), suburb nvarchar(30)) 
    insert into @Test1 values ('Austin', 'Bastrop') 
    insert into @Test1 values ('Austin', 'Hutto') 
    insert into @Test1 values ('Austin', 'Lakeway') 
    insert into @Test1 values ('Austin', 'Luling') 
    insert into @Test1 values ('Austin', 'ShadyHollow') 
    insert into @Test1 values ('Austin', 'WellsBranch') 
    insert into @Test1 values ('Austin', 'BrushyCreek') 
    insert into @Test1 values ('Austin', 'Elgin') 
    insert into @Test1 values ('Austin', 'Jollyville') 
    insert into @Test1 values ('Dallas', 'Belmont') 
    insert into @Test1 values ('Dallas', 'Eastwood') 
    insert into @Test1 values ('Dallas', 'GreenlandHills') 
    insert into @Test1 values ('Dallas', 'LakeParkEstates') 
    insert into @Test1 values ('Dallas', 'Lochwood') 

    declare @Test2 table(city nvarchar(10), vehicle nvarchar(30))

    insert into @Test2 values ('Austin', 'Mercedes-Benz') 
    insert into @Test2 values ('Dallas', 'BMW') 
    insert into @Test2 values ('Dallas', 'Ford') 



select * from @Test0 t0 join @Test1 t1 on t0.city = t1.city 
join @Test2 t2 on t0.city = t2.city 

从哪里开始吗？枢轴的答案是什么？我甚至还在旋转？ 谢谢
