小编use*_*611的帖子

我有一个有两列的表

Order | CustomerID

 1. A | C1 
 2. B | C1 
 3. C | C1 
 4. D | C2 
 5. B | C3 
 6. C | C3
 7. D | C4

它是一张很长的桌子.我想要一个显示的输出

C1 | C3 | 2  #Customer C1 and Customer C3 share 2 orders (i.e. orders, B & C) 
C1 | C2 | 0   #Customer C1 and Customer C2 share 0 orders 
C2 | C4 | 1   #Customer C2 and Customer C4 share 1 orders (i.e. order, D) …

我正在尝试将查询集数据作为 javascript 变量传递到模板。我知道我正在做一些愚蠢且行不通的事情。
