大家好，请教一个问题：
我前端用的easyui datagrid ：
//初始化表头
$('#' + id).datagrid({
columns: [[
{ field: 'Order_ID', title: '流转单ID', width: 80 },
{ field: 'OrderNo', title: '模号', width: 100 },
{ field: 'SaddleNo', title: '鞍架号', width: 100,editor: 'text' },
{ field: 'Length1', title: '长1mm', width: 100,editor: 'text' },
{ field: 'Length2', title: '长2mm', width: 100,editor: 'text' },
{ field: 'Thickness', title: '厚度mm', width: 100,editor: 'text' },
]],
})
后端返回的数据格式如下：
[
{
"Order_ID": "672",
"OrderNo": 1,
"SaddleNo": "1",
"Length1": "2750",
"Length2": "2750",
"Thickness": "100",
},
{
"Order_ID": "673",
"OrderNo": 2,
"SaddleNo": "3",
"Length1": "2750",
"Length2": "2750",
"Thickness": "100",
},
{
"Order_ID": "674",
"OrderNo": 3,
"SaddleNo": "7",
"Length1": "2750",
"Length2": "2750",
"Thickness": "100",
},
{
"Order_ID": "675",
"OrderNo": 4,
"SaddleNo": "9",
"Length1": "2750",
"Length2": "2750",
"Thickness": "100",
},
]
前端正常显示的效果就是类似这样 数据我随便写了 ：
现在我想 把Length1 Length2 Thickness都相等的合并成一行 并且添加一列显示相同的行数 如下：
请教大家 我前端怎么实现 谢谢了
