1.实现效果

2.封装table表格组件

test1.vue

<template>
  <el-table-column :label="coloumnHeader.label" :prop="coloumnHeader.label">
    <template v-for="item in coloumnHeader.children">
      <tableColumn
        v-if="item.children && item.children.length"
        :key="item.id"
        :coloumn-header="item"
      ></tableColumn>
      <el-table-column
        v-else
        :key="item.name"
        :label="item.label"
        :prop="item.prop"
      >
         //悬浮展示详情
       <template slot-scope="scope">
             <el-popover
                placement="top-start"
                width="200"
                trigger="click"
                content="这是一段内容,这是一段内容,这是一段内容,这是一段内容。"
              >
                  <el-button type="text" slot="reference">                
                      {{scope.row[scope.column.property]}}
                  </el-button>
              </el-popover>
          </template>
      </el-table-column>
    </template>
  </el-table-column>
</template>

<script>
export default {
  name: "tableColumn",
  props: {
    coloumnHeader: {
      type: Object,
      required: true,
    },
  },
};
</script>

<style scoped>
</style>

  test2.vue

<template>
  <el-table :data="tableData">
    <template v-for="item in tableHeader">
      <table-column
        v-if="item.children && item.children.length"
        :key="item.id"
        :coloumn-header="item"
      ></table-column>
      <el-table-column
        v-else
        :key="item.id"
        :label="item.label"
        :prop="item.prop"
      >
     </el-table-column>
    </template>
  </el-table>
</template>

<script>
import TableColumn from "./test1.vue";
export default {
  props: {
    // 表格的数据
    tableData: {
      type: Array,
      required: true,
    },
    // 多级表头的数据
    tableHeader: {
      type: Array,
      required: true,
    },
  },
  components: {
    TableColumn,
  },
};
</script>

<style scoped>
.el-button{
  border: none;
  padding: 0;
  color: #606266;
}
</style>

test3.vue 调用组件使用

<template>
  <div>
    <dynamic-table
      :table-data="tableData"
      :table-header="tableConfig"
    ></dynamic-table>
  </div>
</template>

<script>
import DynamicTable from "./test2.vue";
export default {
  components: {
    DynamicTable,
  },
  data() {
    return {
      // 表数据
      tableData: [
        {
          date: "2021-09-06",
          name: "张三",
          phone: "15739951445",
          province: "河北省",
          city: "张家口",
          address: "河北省张家口市桥西区",
        },
      ],
      // 表头数据
      tableConfig: [
        {
          id: 100,
          label: "日期",
          prop: "date",
        },
        {
          id: 200,
          label: "配送信息",
          prop: "",
          children: [
            {

              children:[

                  },

                  },
              ]
            },
            {

              ]
            },
