title: bootstrap-table fixed header not working
body: <p>I have used <code>bootstrap-table</code> to set a table in my project. Everything works fine except scroll bar inside the <code>tbody</code>.   </p>
  
  <p>There is no scroll bar there. What am I missing? I believe if the scroll-bar is visible then the <code>fixed-header</code> for the table feature should also work fine. </p>
  
  <pre><code>&lt;table id="tblMain" class="table table-bordered table-hover" data-show-refresh="false" data-click-to-select="false" data-single-select="true" data-show-toggle="false" data-show-columns="false" data-cache="false" data-page-number="@Model.CommonVariable" data-url='@Url.Action("Index", "Home")'  data-side-pagination="server" data-pagination="true" data-search="false" data-query-params="queryParams" data-response-handler="respHandler"&gt;
      &lt;thead class="table-head"&gt;
          &lt;tr&gt;
              &lt;th data-field="id" data-formatter="SomeFunction"&gt;Item ID&lt;/th&gt;
              &lt;th data-field="name" data-formatter="SomeFunction2"&gt;Item Name&lt;/th&gt;
              &lt;th data-field="price" data-formatter="SomeFunction3"&gt;Item Price&lt;/th&gt;
          &lt;/tr&gt;
      &lt;/thead&gt;
  &lt;/table&gt;
  </code></pre>
