The table has a css class of jlad_shortcode_table, so you can style it with css, for example:
<pre><code>`
</code></pre>
.jlad_shortcode_table thead, 
.jlad_shortcode_table tfoot { 
 background-color: #000077; 
 color: #FFFFFF; 
}
.jlad_shortcode_table tr:nth-child(even) { 
 background-color: #f2f2f2; 
}
.jlad_shortcode_table td:last-child { 
 text-align: center; 
 width: 20%; 
}
.jlad_shortcode_table tfoot td:first-child { 
 text-align: right; 
} 
 `
Creates a table with blue background and white text header/footer rows, zebra stripes on the post list, centers the likes/dislikes column and aligns the “Total” in the footer to the right of the column.
<h4>Custom Function</h4>
<pre><code><?php echo do_shortcode('[just_like_and_dislike id=post_id]');?>
</code></pre>
Please replace post_id with the id of the post or remove id parameter for considering the post id as the id of global $post object
