+            <p>When you set the <code>height</code> of bootstrap table, the <code>fixed header</code> feature is automatically enabled, that is what cause the problem, you need to listen the <code>resize</code> event of window and use the <code>resetView</code> method to solve this problem, code example:</p>
+
+<pre><code>$(function () {
+    $('#tableId').bootstrapTable(); // init via javascript
+
+    $(window).resize(function () {
+        $('#tableId').bootstrapTable('resetView');
+    });
+});
