Avue.js 是基于现有的element-ui库进行的二次封装，从而简化一些繁琐的操作，核心理念为数据驱动视图,主要的组件库针对table表格和form表单场景，同时衍生出更多企业常用的组件，达到高复用，容易维护和扩展的框架，同时内置了丰富了数据展示组件，让开发变得更加容易.

前言

在实际开发过程，需要多级复杂的动态表头，表头中的内容是动态填充的。以下是avuejs官网提供的负责表头样式，因此我后台返回的数据，需要拼接avue-crud中的json格式。

实际开发中需要拼接成，column这种格式。

column: [{
            label: '姓名',
            prop: 'name',
            width:140,
          }, {
            label: '性别1',
            prop: 'sex',
          },
          {
            label: '自定义图标',
            prop: 'icon',
            type: "icon",
            iconList: [{
              label: '基本图表',
              list: ['el-icon-time', 'el-icon-bell', 'el-icon-star-on']
            }]
          }, {
            label: '复杂表头',
            children: [{
              label: '信息',
              children: [{
                label: '年龄',
                prop: 'age'
              }, {
                label: '手机号',
                prop: 'phone',
              }]
            }, {
              label: '地区',
              prop: 'address',
              type: 'select',
              props: {
                  label: 'name',
                  value: 'code'
              },
              dicUrl:'https://cli.avuejs.com/api/area/getProvince'
            }]
          }, {
            label: '测试',
            prop: 'test',
          },
          {
            label: '手机信息1',
            prop: 'phone1'
          }],
        },
        data: [{
          name: '张三',
          age: 14,
          address: '110000',
          phone1: '17547400800',
          phone: '17547400800',
          icon: 'el-icon-time',
          test: 1,
          sex: '男'
        }, {
          name: '王五',
          age: 10,
          address: '120000',
          test: 1,
          sex: '女',
          icon: 'el-icon-star-on',
          phone1: '17547400800',
          phone: '17547400800'
        }]

后台数据拼接

@GetMapping("/getTableHeader")
	public R getTableHeaderJson(){
		Map<String,Object> map = new HashMap<>();
		StringBuilder sb = new StringBuilder();
		sb.append("{label: '工序',children: [");
		List<FactoryProcess> processList = factoryProcessService.list();
		for (int i = 0; i < processList.size(); i++) {
			String pid = processList.get(i).getProcessId();
			sb.append("{label:'" + processList.get(i).getProcessName() + "',prop:'" + pid + "',");
			sb.append("children:[{label: '单价',prop: 'price" + pid + "'}, " +
				"{label: '合计',prop: 'sum" + pid + "'},{label: '完成数量',prop: 'completeNum" + pid + "'}, " +
				"{label: '质检合格数量',prop: 'qualifiedNum" + pid + "'}," +
				" {label: '质检不合格数量',prop: 'unqualifiedNum" + pid + "'}, " +
				"{label: '报废数量',prop: 'scrapNum" + pid + "'}]").append("},");
		};
		sb.append("]}");

		map.put("cols",sb.toString());

		return R.data(map);
	}

前台数据展示

在created函数中加载表头信息展示

// created生命周期函数中加载
created(){
      this.getHeaderList();
 },
//method中加载页面展示的信息 
methods: {
      getHeaderList(){
        getHeaderFun().then(res => {
          this.option.column.push(
                 {
                   label: "产品名称",
                   prop: "productName",
                   color:'#eef1f6'
                 },
                 {
                   label: "产品代号",
                   prop: "productCode",
                 },
                 {
                   label: "材质",
                   prop: "productMaterialStr",
                 },
                 {
                   label: "数量",
                   prop: "sumNum",
                 },
                 {
                   label: "外协数量",
                   prop: "outNum",
                 },
                 {
                   label: "外协完成量",
                   prop: "outCompleteNum"
                 },
                 {
                   label: "总完成量",
                   prop: "totalCompleteNum"
                 }
          )
          // 得到后台拼接的信息
          let objs =  eval("("+res.data.data.cols+")");
          this.option.column.push(objs);
          this.onLoad(this.page);
        })
      }, 
 }

加载表格中的数据

// 页面数据的展示，需要于后台请求的prop属性对应
onLoad(page, params = {}) {
        this.loading = true;
        findProjectFormList(page.currentPage, page.pageSize, Object.assign(params, this.query)).then(res => {
          const data = res.data.data;
          this.page.total = data.total;
          //this.data = data.records;

          let records = data.records;
          let dataList = [];
          let processList = this.option.column[7].children;
          for(let i = 0; i < records.length; i++ ) {
            let obj = {
              'productName' : records[i].productName,
              'productCode' : records[i].productCode,
              'productMaterialStr' : records[i].productMaterialStr,
              'sumNum' : records[i].sumNum,
              'outNum' : records[i].outNum,
              'outCompleteNum' : records[i].outCompleteNum,
              'totalCompleteNum': records[i].totalCompleteNum,
            }
            let processNumList = records[i].processNumList;
            for(let j = 0; j < processNumList.length; j++) {
              for (let k = 0; k < processList.length; k++) {
                if (processList[k].prop === processNumList[j].processCode) {
                // $set向相应的属性prop中赋值
                  this.$set(obj, 'price'+processNumList[j].processCode, processNumList[j].processPrice);
                  this.$set(obj, 'sum'+processNumList[j].processCode, processNumList[j].processTotal);
                  this.$set(obj, 'completeNum'+processNumList[j].processCode, processNumList[j].completeNum);
                  this.$set(obj, 'qualifiedNum'+processNumList[j].processCode, processNumList[j].qualifiedNum);
                  this.$set(obj, 'unqualifiedNum'+processNumList[j].processCode, processNumList[j].unqualifiedNum);
                  this.$set(obj, 'scrapNum'+processNumList[j].processCode, processNumList[j].scrapNum);
                  this.$set(obj, 'shift'+processNumList[j].processCode, processNumList[j].shiftName);
                }
              }
            }
            dataList.push(obj);
          }
          this.data = dataList;

          this.loading = false;
          this.selectionClear();

        })
      },
