Make table 100% width if parents have width in percent
<p>I have issues with 100% width of table, I have div content width in pixels, then all sub divs are in percent and work good, but table doesn't. </p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-css lang-css prettyprint-override"><code>   #content{
        position: fixed;
        float: left;
        top: 116px;
        width: calc(100% - 125px);
        height: calc(100% - 124px);
        background-color: #bdc9ce;
    }
    .size-3{
        width: 33.333%;
    }
    .inputs-root{
        width: 100%;
    }
    .input-table{
        width: 100%;
    }</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div id="content"&gt;
       &lt;div class="size-3"&gt;
         &lt;div class="inputs-root"&gt;
           &lt;tbody class="input-table"&gt;
             &lt;tr&gt;....
             &lt;/tr&gt;
           &lt;/tbody&gt;
        &lt;/div&gt;
      &lt;/div&gt;
    &lt;/div&gt;</code></pre>
</div>
</div>
</p>

<p>So I don't know, why is width of table longer than .inputs-root... any tips ?
I tried to set <code>table-layout: fixed;</code> and <code>word-break</code> too but still same </p>

<p><strong>EDIT</strong></p>

<p><strong>MY CODE :</strong></p>

<p>Render of entire list of inputs - <a href="http://pastebin.com/jZvzdgyT" rel="nofollow noreferrer">http://pastebin.com/jZvzdgyT</a></p>

<p>Render of single inputs - <a href="http://pastebin.com/DEmAdiD2" rel="nofollow noreferrer">http://pastebin.com/DEmAdiD2</a>
its writed in reactjs, so just look on render methods</p>
