我有一个窗口，名为窗口1，里面有4个控件 其中有一个ListView的控件

我需要将表里的规格“S,M,L”作为ListView里的列显示，（“S,M,L”非固定的数据，有可能是“F”，也有可能是“XS,S,M,L,XL”等），箱号列也会有不同如果连续的箱号，装的款号一样，颜色一样，规格一样则箱号合并，比如说1号箱和2号箱装的款号一样，颜色一样，规格一样，则显示为1~2，不连续的则分开

请问这个代码怎么写

请看懂代码，理解代码以后，自己修改。示例代码已经写出来给你。自己改动一下。

请问如何去掉图片中连续箱号中间的数字，让它只显示头箱和尾箱。也就是如果是4-5-6-7-8装箱数颜色规格一样的同类产品，只显示 4-8 ，表示第4箱到第8箱的数量规格颜色一致
