javascript - 空分组 Jqgrid - 没有项目的组

Question

jqgrid 中是否可以有没有项目(0 项目)的分组的网格？

例如，我想添加一个没有项目的 test4 组，并且可以使用分页和排序。

var mydata = [
		{id:"1",invdate:"2010-05-24",name:"test",note:"note",tax:"10.00",total:"2111.00"} ,
		{id:"2",invdate:"2010-05-25",name:"test2",note:"note2",tax:"20.00",total:"320.00"},
		{id:"3",invdate:"2007-09-01",name:"test3",note:"note3",tax:"30.00",total:"430.00"},
		{id:"4",invdate:"2007-10-04",name:"test",note:"note",tax:"10.00",total:"210.00"},
		{id:"5",invdate:"2007-10-05",name:"test2",note:"note2",tax:"20.00",total:"320.00"},
		{id:"6",invdate:"2007-09-06",name:"test3",note:"note3",tax:"30.00",total:"430.00"},

Answer 1

不，这是不可能的。 jqGrid 按 groupingView.groupField 作为第一个排序字段，按 sortname 作为第二个排序名称对数据项进行排序。排序结果将显示在网格中。与标准网格的唯一区别是在数据之前插入带有分组标题的附加行。分组标题包含“+”图标，用于隐藏/显示组的数据行。

您当然可以在网格中间添加任何自定义行，这看起来像分组标题，但您必须自己管理所有事情。例如，您必须决定需要在哪个页面上以及哪个位置插入自定义行。
