原理是将原table的指定行,指定列clone一份放在其上

实现代码如下:

<template>  <div>   <div id="divBox1" :style="{height:height}">    <table id="tbTest1" cellpadding="0" cellspacing="0" style="text-align:center;background:rgba(244,249,255,0.4);">     <tr>      <th v-for="item in thead" @click="sortBy(item)">       {{item}}<img style="width:0.16rem;height:0.20rem;margin-left:4px;" :src="filterUrl" alt="" v-if="$index!=0" data-img="{{filterUrl}}">      </th>     </tr>     <tr v-for="row in tableRows | orderBy sortBykey sortOrders[sortKey]">      <td style="overflow:hidden;white-space:nowrap;" v-for="item in gridColumns" v-html="row[item] | numberFilter" :id="$parent.$index">      </td>     </tr>    </table>   </div>  </div> </template> <script>  /*eslint-disable*/  var ofixed_table_st = window.setTimeout;  var hasLeft = '';  var hasHead = '';  window.setTimeout = function(fRef, mDelay) {   if(typeof fRef == 'function') {    var argu = Array.prototype.slice.call(arguments, 2);    var f = (function() {     fRef.apply(null, argu);    });    return ofixed_table_st(f, mDelay);   }   return ofixed_table_st(fRef, mDelay);  };  function oFixedTable(id, obj, _cfg) {   this.id = id;   this.obj = obj;   this.box = this.obj.parentNode;   this.config = {    fixHead: _cfg.fixHead || true,    rows: _cfg.rows || 1,    cols: _cfg.cols || 0,    background: _cfg.background || '#ffffff',    zindex: _cfg.zindex || 10   };   window.setTimeout(this._fixTable, 100, this);

 }  #tbTest1 tr td:nth-child(1){   box-shadow: #dddddd 2px 0px 0px;  }  #tbheader td {   background: #fff;  } </style> 

父组件调用实例:

<template>    <table-locked :table-rows="tableData" :grid-columns="gridColumns" :thead="thead" :height="height">    </table-locked> </template> import TableLocked from '../../common/TableLocked.vue' export default{   components: {TableLocked},   data () {     data.gridColumns = ['brand', 'product_count', 'averagePrice', 'sales', 'huang_sale_per', 'sale_per', 'sales_amount', 'huang_sale_amount_per', 'sales_amount_per', 'score_num', 'scort_good_per']    data.thead = ['品类', '产品种类', '均价', '销量', '销量环比', '销量占比', '销额(万元)', '销额环比', '销额占比', '评论总数', '好评率']   } }
