问题描述

我下面列出了数据库.如您所见，每种型号都有多年的范围.例如，在2008-2010

I've got database listed below. As you can see, there is a range of years for each model. For example, Infiniti EX35 in range of 2008-2010

Infiniti    EX35    2010    3.5 V6
Infiniti    EX35    2009    3.5 V6
Infiniti    EX35    2008    3.5 V6
Infiniti    EX37    2007    3.7i V6
Infiniti    EX37    2008    3.7i V6
Infiniti    EX37    2009    3.7i V6
Infiniti    EX37    2010    3.7i V6
Infiniti    FX35    2003    3.5 V6
Infiniti    FX35    2004    3.5 V6
Infiniti    FX35    2005    3.5 V6
Infiniti    FX35    2006    3.5 V6
Infiniti    FX35    2007    3.5 V6
Infiniti    FX35    2008    3.5 V6

如何进行这样的紧凑选择?

How can I make compact selection like this?

Infiniti    EX35    2008-2010   3.5 V6
Infiniti    EX37    2007-2010   3.7i V6
Infiniti    FX35    2003-2008   3.5 V6

谢谢！
