<p dir="auto">This issue occured when we upgraded to bootstrap 3.1.</p>
<p dir="auto">jsfiddle: <a href="http://jsfiddle.net/kKsp7/2/" rel="nofollow">http://jsfiddle.net/kKsp7/2/</a></p>
<p dir="auto">The hack I will use until this issue is fixed is included in the css.</p>
<p dir="auto">As of 3.1, when you do:</p>
<div class="highlight highlight-text-html-basic notranslate position-relative overflow-auto" dir="auto" data-snippet-clipboard-copy-content="&lt;div class=&quot;panel panel-default&quot;&gt;
  &lt;table class=&quot;table table-bordered&quot;&gt;
    &lt;thead&gt;
      &lt;th&gt;foo&lt;/th&gt;
    &lt;/thead&gt;
    &lt;tbody&gt;
      &lt;tr&gt;
        &lt;td&gt;baz&lt;/td&gt;
      &lt;/tr&gt;
    &lt;/tbody&gt;
  &lt;/table&gt;
&lt;/div&gt;"><pre class="notranslate"><span class="pl-kos">&lt;</span><span class="pl-ent">div</span> <span class="pl-c1">class</span>="<span class="pl-s">panel panel-default</span>"<span class="pl-kos">&gt;</span>

<p dir="auto">You get no border between the head and the body like in <code class="notranslate">3.0.x</code>. It comes back if you remove <code class="notranslate">table-bordered</code> but then you don't have vertical separators between columns.</p>
