how to reduce white space(right width) in my box - html

Question

Hello I have two contents in my table, so two boxes that contain contents in html. I want to reduce the distance between these two boxes, but I realized size of one box is too big that they are just white space. I'm having trouble reducing that size. can someone please help me with this?
so, cell x and cell y that's in same row to be located closer.
<table class="table">
<tr id="cell">
---------------------------------------------------------------(one cell)
<td class="vert-align">
<div class="voting-space">
<a href="/post/{{ post.slug }}/vote?is_up=1" class="vote">
<span class="glyphicon glyphicon-triangle-top col-md-12" aria-hidden="true"></span></a>
<br />
<span class="col-md-12" style="height:1px; font-family: 'Passion One', cursive; bottom:10px; padding-left:0.01em;
"><h4 id="vote_count_{{ post.slug }}">{{ post.get_vote_count }}</h4></span> <br>
<a href="/post/{{ post.slug }}/vote?is_up=0" class="vote">
<span class="glyphicon glyphicon-triangle-bottom col-md-12" aria-hidden="true"></span></a>
</div>
</td>
--------------------------------------------------------------------(the other cell)
<td class="vert-align">
{% if post.url %}
<h4 id="line">
<img src="{{post.image}}" height="85" width="85"/><span id="title-font">{{ post.title }}</span>
<span style="margin-left: 15px;" class="domain">({{ post.domain }})</span>
<span class="discuss" style="color:red;">토론장 입장</span>
<br />
<span class="post-info">{{ post.pub_date | timesince }}전/{{ post.moderator.username }}작성/<i class="fa fa-eye"></i>{{post.views}}/{{post.category}}</span>
</h4>
{% else %}

For controlling "cellpadding" in CSS, you can simply use padding on table cells. E.g. for 10px of "cellpadding":
td {
padding: 10px;
}
For "cellspacing", you can apply the border-spacing CSS property to your table. E.g. for 10px of "cellspacing":
table {
border-spacing: 10px;
border-collapse: separate;
}
This property will even allow separate horizontal and vertical spacing, something you couldn't do with old-school "cellspacing".
