<script>   $('td').hover(function() {  $(this).parents('table').find('col:eq('+$(this).index()+')').toggleclass('hover'  ); });   </script>   <style type="text/css">  body {    font: 16px/1.5 helvetica, arial, sans-serif; }  table { width: 80%; margin: 20px auto; border-collapse: collapse; } table th { text-align: left; } table tr, table col { transition: .3s; } table tbody tr:hover { background-color: rgba(0, 140, 203, 0.2); } table col.hover { background-color: rgba(0, 140, 203, 0.2); }    </style>     <div style="width:700px;">  <table> <col /> <col /> <col /> <col /> <thead>   <tr>     <th>name</th>   <th>age</th>   <th>birthdate</th>   <th>preferred hat style</th>  </tr>   </thead>   <tbody>   <tr>   <td>abraham lincoln</td>   <td>204</td>   <td>february 12</td>   <td>stovepipe</td>   </tr>    <tr>   <td>winston churchill</td>   <td>139</td>   <td>november 30</td>   <td>homburg</td>   </tr>   <tr>   <td>rob glazebrook</td>   <td>32</td>   <td>august 6</td>   <td>flat cap</td>   </tr>   </tbody>  </table>  </div>

add class table, example my-table. , use in js - $(this).parents('.my-table').

// css newbie article here:  // http://www.cssnewbie.com/simple-table-column-highlighting/    $('td').hover(function() {   $(this).parents('.my-table').find('col:eq('+$(this).index()+')').toggleclass('hover');  });
body {    font: 16px/1.5 helvetica, arial, sans-serif;  }    table {    width: 80%;    margin: 20px auto;    border-collapse: collapse;  }  table th {    text-align: left;  }  table tr, table col {    transition: .3s;  }  table tbody tr:hover {    background-color: rgba(0, 140, 203, 0.2);  }  table col.hover {    background-color: rgba(0, 140, 203, 0.2);  }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <table class="my-table">    <col />    <col />    <col />    <col />    <thead>      <tr>        <th>name</th>        <th>age</th>        <th>birthdate</th>        <th>preferred hat style</th>      </tr>    </thead>    <tbody>      <tr>        <td>abraham lincoln</td>        <td>204</td>        <td>february 12</td>        <td>stovepipe</td>      </tr>      <tr>        <td>winston churchill</td>        <td>139</td>        <td>november 30</td>        <td>homburg</td>      </tr>      <tr>        <td>rob glazebrook</td>        <td>32</td>        <td>august 6</td>        <td>flat cap</td>      </tr>    </tbody>  </table>
