iview给table组件添加自增序号

傻逼了，iview自带了自增序号，还是记录一下吧
template:

          <Table
            :columns="informationTable"
            :data="informationData"
          ></Table>

data:
type: 'index',

        {
    
    
          title: '序号',
          type: 'index',
          width: 60,
          align: 'left'
        },

informationTable: [
        {
    
    
          title: '序号',
          width:80,
          render:(h,params)=>{
    
    
            return h("span" ,{
    
    
            },params.index+1)
          }
        },
        {
    
    
          title: "申请单号",
          key: "Code",
          width: 100,
          align: "center"
        },
        {
    
    
          title: "会员名称",
          key: "Name",
          width: 100
        }
   ],
   informationData: [
	  {
    
    
	    Code: '200',
	    Name: "aaa"
	  },
	  {
    
    
	    Code: '200',
	    Name: "aaa"
	  },
	  {
    
    
	    Code: '200',
	    Name: "aaa"
	  }
	]

效果：
