Styler render creates extra indent which when exported to markdown becomes a code block 
#### Code Sample, a copy-pastable example if possible

```python
# Your code here
In [12]: df
Out[12]:
   A       B       C
0  1  0.5021 -1.8989
1  0 -0.0123  0.4893
2  0 -1.0470 -0.9169

In [13]: print(df.style.set_caption('example').render())

        <style  type="text/css" >


        </style>

        <table id="T_abffa708_05f4_11e7_920b_acbc329287af" None>

            <caption>example</caption>


        <thead>

            <tr>


                <th class="blank level0" >




                <th class="col_heading level0 col0" colspan=1>
                  A
```
#### Problem description

Although the above output renders fine in an ipython notebook, when that notebook is then exported to markdown, the indent is interpreted as a code block so the output HTML renders as a code block 

#### Expected Output

Same thing, just no indent.
