多级表头表格封装

1、表格组件封装

本例子只写到第三层，可自行拓展

<template>
  <div>
    <el-table :data="tableData" border style="width: 100%">
      <!-- 第一级表头列  -->
      <el-table-column
        v-for="column in tableColumns"
        :key="column.label"
        :label="column.label"
        :align="column.align || 'center'"
        :min-width="column.minWidth"
        show-overflow-tooltip
      >
        <template v-if="column.children">
          <!-- 第二级表头列 -->
          <el-table-column
            v-for="child in column.children"
            :key="child.label"
            :label="child.label"
            :prop="child.prop"
            :min-width="child.minWidth"
          >
            <template v-if="child.children">
              <el-table-column
                v-for="subchild in child.children"
                :key="subchild.label"
                :label="subchild.label"
                :prop="subchild.prop"
                :min-width="subchild.minWidth"
              >
              </el-table-column>
            </template>
            <template v-else>
              <el-table-column :prop="column.prop"></el-table-column>
            </template>
          </el-table-column>
        </template>
        <template v-else>
          <el-table-column :prop="column.prop"></el-table-column>
        </template>
      </el-table-column>
    </el-table>
  </div>
</template>

<script>
export default {
  data() {
    return {
      tableData: [
        {
          secondPlayer1: "aaa",
          thirdPlayer1: "111",
          thirdPlayer2: "222",
        },
      ], // 表格数据数组
      tableColumns: [
        // 表头配置数组
        {
          label: "序号",
          type: "index",
          width: "70",
        },
        {
          label: "第一级表头",
          // prop: 'finstPlayer',
          minWidth: "",
          children: [
            {
              label: "第二级表头1",
              prop: "secondPlayer1",
              minWidth: "",
            },
            {
              label: "第二级表头2",
              prop: "secondPlayer2",
              minWidth: "",
              children: [
                {
                  label: "第三级级表头1",
                  prop: "thirdPlayer1",
                  minWidth: "",
                },
                {
                  label: "第三级级表头2",
                  prop: "thirdPlayer2",
                  minWidth: "",
                },
              ],
            },
          ],
        },
      ],
    };
  },
  created() {},
  methods: {},
};
</script>

<style scoped>
/* 表格上方留出间距 */
.el-table {
  margin-top: 20px;
}
</style>

2、实现效果
