由于项目中频繁的使用表格，会出现非常多的重复代码，所以决定对element-plus的table表格、Pagination分页进行二次封装，尽量避免代码冗余。代码如下：

1、在components文件下新建CommonTable/CommonTable.vue文件

<template>
  <div class="table">
    <el-table
      :data="tableData"
      border
      style="width: 100%"
      max-height="300"
      v-loading="loading"
      @selection-change="selectionChange"
    >
      <el-table-column type="selection" width="50" />
      <template v-for="(item, index) in tableHeader">
        <!-- 插槽：标题文字要特殊显示 | 操作 -->
        <el-table-column
          v-if="item.slot"
          :key="index"
          :prop="item.prop"
          :label="item.label"
          :fixed="item.fixed"
          :align="item.align || 'center'"
          :show-overflow-tooltip="item.overHidden || false"
          :min-width="item.minWidth || '100px'"
          :sortable="item.sortable || false"
          :type="item.type"
          :width="item.width"
        >
          <slot :name="item.slot"></slot>
        </el-table-column>
        <!-- 文字不需要特殊显示 -->
        <el-table-column
          v-else
          :key="index + 1"
          :prop="item.prop"
          :label="item.label"
          :fixed="item.fixed"
          :align="item.align || 'center'"
          :show-overflow-tooltip="item.overHidden || false"
          :min-width="item.minWidth || '100px'"
          :sortable="item.sortable || false"
          :type="item.type"
          :width="item.width"
        >
          <template #default="scope">
            <span>{{ scope.row[item.prop] ? scope.row[item.prop] : "" }}</span>
          </template>
        </el-table-column>
      </template>
    </el-table>
    <!-- 分页 -->
    <el-pagination 
    :locale="locale"
      background
      class="pagination"
      small
      :page-sizes="pageSizesArr"
      @size-change="sizeChange"
      @current-change="currentChange"
      :current-page="current"
      :page-size="size"
      :total="total"
      :layout="layout"
    />
  </div>
</template>
    
<script setup lang='ts'>
import { defineProps, defineEmits, onMounted, reactive, ref } from "vue";


const emits = defineEmits(["selectionChange", "sizeChange", "currentChange"]);
const props = defineProps({
  // 表格显示的数据
  tableData: {
    type: String,
    // default: function () {
    //   return [];
    // },
  },
  // 表头数据
  tableHeader: {
    type: String,
    default: function () {
      return [];
    },
  },
  // 总页数
  total: {
    type: Number,
    // 类型
    required: true,
    default: 0,
  },
  // 分页的页容量数组
  pageSizesArr: {
    type: Array,
    default() {
      return [10, 20, 30, 50];
    },
  },
  // 分页的布局
  layout: {
    type: String,
    default: "total, sizes, prev, pager, next, jumper",
  },
});
//表格事件
const selectionChange = (val) => {
  emits("selectionChange", val);
};

// 页数改变的时候触发的事件
const sizeChange = (val) => {
  emits("sizeChange", val);
};
// 当前页改变的时候触发的事件
const currentChange = (val) => {
  emits("currentChange", val);
};
</script>
    
<style lang="less" scoped>
.table {
  margin-top: 1rem;
}
.pagination {
  float: right;
  margin-top: 1.25rem;
  margin-bottom: 1.25rem;
}
</style>

2、组件中使用

<template>
  <el-card class="main-card">
    <!-- 表格展示 -->
    <CommonTable
      :tableData="tableData"
      :tableHeader="tableHeader"
      :isOperate="isOperate"
      :total="total"
      :operateWidth="operateWidth"
      @handleSizeChange="sizeChange"
      @handleCurrentChange="currentChange"
    >
    <template v-slot:isReview>
          <el-tag v-if="isReview == 0" type="warning">审核中</el-tag>
          <el-tag v-if="isReview == 1" type="success">正常</el-tag>
    </template>
    <template v-slot:state>
        <el-tag v-if="state == 1">文章</el-tag>
          <el-tag v-if="state == 2" type="danger">留言</el-tag>
          <el-tag v-if="state == 3" type="success">关于我</el-tag>
          <el-tag v-if="state == 4" type="warning">友链</el-tag>
          <el-tag v-if="state == 5" type="warning">说说</el-tag>
    </template>
    <template v-slot:action>
          <el-button
            v-if="action == 0"
            size="mini"
            type="success"
            @click="updateCommentReview(scope.row.id)">
            通过
          </el-button>
          <el-popconfirm style="margin-left: 10px" title="确定删除吗？" @confirm="deleteComments(scope.row.id)">
            <el-button size="mini" type="danger"> 删除 </el-button>
          </el-popconfirm>
        </template>
    </CommonTable>
  </el-card>
</template>
    
<script setup lang='ts'>
