1、话不多说先看成果

次要实现性能：筛选：输入框、下拉框、工夫；表格实用：多选、序号、排序、自定义、开关、链接可跳转、输入框、图片、自定义操作按钮（局部页面须要每行显示按钮不必所以大家按需增加）、惯例操作按钮（每行操作按钮都雷同无其余需要）、设置行背景色、分页

2、本文局部原创，大框架是复制的 https://blog.csdn.net/qq_37346639/article/details/115556605 这个博客，因为懒的本人写😂，依照需要改为本人所须要格局

3、筛选组件代码 

<template>
    <div>
      <ul class="row-list" v-if="screenConfig.searchShow">
        <li v-for="(item,index) in screenConfig.formItem" :key="index">
          <label v-if="item.type !='operationBtn'">{{item.label}}：</label>
<!--          输入框 -->
          <el-input v-if="item.type ==='input'"clearable v-model.trim="screenConfig.searchParams[item.prop]"class="w215"size="small":placeholder="item.placeholder"></el-input>
<!--          下拉框 -->
          <el-select v-if="item.type ==='select'"filterable clearable v-model.trim="screenConfig.searchParams[item.prop]":placeholder="item.placeholder"size="small":multiple="item.multiple":filterable="item.filterable">
            <el-option v-for="selectItem in item.options" :key="selectItem[item.value]" :value="selectItem[item.value]"
                       :label="selectItem[item.leftLabel]" :disabled="selectItem.disabled">
              <span style="float: left">{{selectItem[item.leftLabel] }}</span>
              <span style="float: right; color: #8492a6; font-size: 13px">{{selectItem[item.rightLabel] }}</span>
            </el-option>
          </el-select>
<!--          工夫选择器 -->
          <el-date-picker v-if="item.type ==='datePicker'"clearable v-model="screenConfig.searchParams[item.prop]":type="item.dateType"size="small":value-format="item.format"placeholder=" 请抉择 "range-separator=" 至 "start-placeholder=" 开始日期 "end-placeholder=" 完结日期 ">
          </el-date-picker>
<!--          自定义 -->
          <slot v-if="item.type =='custom'"name='customFilter'></slot>
          <!--          按钮 -->
          <span v-if="item.type =='operationBtn'"v-for="(operations, index) in item.operation":key="index">
                        <el-button v-if="operations.isShow" :type="operations.btnType"  :icon="`iconfont ${operations.icon}`"
                       @click="screenBtn(operations)" class="screen-btn" :disabled="operations.disabled"
                       size="mini">{{operations.label}}
            </el-button>
                    </span>
        </li>
      </ul>
    </div>
</template>

<script>
  export default {
    name: "PublicFilter",
    props: {
      screenConfig: {
        type: Object,
        required: true
      },
    },
    data() {return {};
    },
    methods: {
      // 操作按钮
      screenBtn(data) {this.$emit("screenBtn",data)
      }
    },
  }
</script>

<style scoped lang="less">
.screen-btn {margin-right: 10px;}
.row-list {
  li{
    margin-bottom: 15px;
    float: left;
    margin-right: 15px;
    min-height: 32px;
    line-height: 32px;
  }
}
</style>

4、表格组件代码 

<template>
  <div>
    <el-table size="medium" :data="tableData" :stripe="false" :border="false" :fit="true"
              :header-cell-style="{background:columnObj.headerBgColor,color: columnObj.headerColor,height: columnObj.headerHigh}"

          <!-- 自定义内容 -->
          <slot v-if="column.type =='ownDefined'"name='ownDefined':row="row,column"></slot>

    </div>
  </div>
</template>

<script>
  export default {
    name: 'public-table',
    props: {
      tableData: {
        type: Array,

      },
      columnObj: {

      selectable(row, index) {if (row.switchs) {return true;}
        this.$emit("selectable", row, index)
      },
      // 操作按钮
      rowOperation(row, $index, now) {this.$emit("rowOperation", row, $index, now)

      // 行的 className 的回调办法
      tableRowClassName({row, rowIndex}) {row.rowIndex = rowIndex;},

  }
</script>
<style lang="less" scoped>
  .el-button {margin: 0 6px;}
  .page_div {padding: 15px 0;}
  .url {
    color: #3d8de0;
    cursor: pointer;
  }
  /deep/.el-table__body tr.current-row>td.el-table__cell {background-color: #a8b9cc;}
  /deep/.el-table--enable-row-hover .el-table__body tr:hover>td.el-table__cell {color: #606266;}
</style>

5、全局引入组件 

**main.js** 页面全局引入组件或单页面引入看需要，我是全局引入


import {PublicTable,PublicFilter} from '@/components';

Vue.component(PublicTable.name,PublicTable);
Vue.component(PublicFilter.name,PublicFilter);

文件目类
[图片上传失败 …(image-70848a-1662602567621)]
components>index.js

import PublicTable from '@/components/PublicTable';
import PublicFilter from '@/components/PublicFilter';

export {PublicTable,PublicFilter};

6、父组件应用 

<template>
  <div class="box">
    <el-card shadow="never">
      <public-filter :screenConfig="screenConfig" @screenBtn="screenBtn">
        <template  slot='customFilter'>
          <el-radio-group v-model="screenConfig.searchParams.aaa" class="radio">
            <el-radio :label="3"> 备选项 </el-radio>
            <el-radio :label="6"> 备选项 </el-radio>
            <el-radio :label="9"> 备选项 </el-radio>
          </el-radio-group>
        </template>
      </public-filter>
    </el-card>
    <el-card shadow="never" class="mt-20">
      <public-table :tableData="tableData" :columnObj="columnObj" :pageObj="pageObj" @rowOperation="rowOperation"
                   @switchChange="switchChange" @editInputBlur="editInputBlur" @rowClick="rowClick"
                    @sortChange="sortChange"
                   @handleSizeChange="handleSizeChange" @handleCurrentChange="handleCurrentChange">
        <template slot='ownDefined' slot-scope="{row,column}">
          <p>
            <span v-if="row.names" :class="`iconfont ${row.names.icon}`" :style="{fontSize: row.names.fontSize,color: row.names.color}"></span>
            {{row.name}}
          </p>
          <p>{{row.address}}</p>
        </template>
      </public-table>
    </el-card>
  </div>
</template>
