원래 테이블의 지정된 행과 열을 복제하여 그 위에 놓는 것이 원칙입니다.

구현 코드는 다음과 같습니다.

<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>
