饿了么表格二次封装具名插槽append的分装实现

1）在封装组件中使用table具名插槽,并自定义具名插槽，对外开发使用:commonTable

<template>
  <div class="common-table-style">
    <el-table
      :data="tableData"
      tooltip-effect="dark"
      border
      highlight-current-row
      :max-height="maxHeight"
      :empty-text="emptyText"
      @sort-change="sortChange"
      @filter-change="filterChange"
      @selection-change="selectionChange"
      ref="commonRef"
    >
      <slot></slot>
      <div slot="append">
      　　<slot name="xxxx"></slot>
      </div>
    </el-table>
  </div>
</template>

<script>

export default {

  props: {

    tableData: {

      type: Array,

      default: () => {}

    },

    maxHeight: {

      type: Number,

      default: null

    },

    emptyText: {

      type: String,

      default: "暂无数据"

    }

  },

  methods: {

    sortChange(e) {

      this.$emit("sortChange", e);

    },

    filterChange(e) {

      this.$emit("filterChange", e);

    },

    selectionChange(e) {

      this.$emit("selectionChange", e);

    }

  }

};

</script>

2）封装组件的使用方法：

<template>
  <div v-loading="loading">
    <sn-table :tableData="entityTableData.list" class="mt20">
      <el-table-column label="名称" prop="name" show-overflow-tooltip></el-table-column>
      <el-table-column label="中文名" prop="entityChName" show-overflow-tooltip></el-table-column>
      <div slot="xxxxx">
        more content
      </div>
    </sn-table>
  </div>
</template>
