这篇文章主要讲解了“avue-crud多级复杂的动态表头怎么实现”，文中的讲解内容简单清晰，易于学习与理解，下面请大家跟着小编的思路慢慢深入，一起来研究和学习“avue-crud多级复杂的动态表头怎么实现”吧！

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();        })      },
