I have a pandas dataframe with three columns of which the first is the Date. To produce a html output I use this: 

```
html_string = df.style.format({'second': "{:0,.0f}",third: "{:0,.0f}"}).set_table_styles(styles).render()

```

how is it possible to specifiy the format of the Date as well...something like:

```
html_string = df.style.format({'Date': "%Y.%m",'second': "{:0,.0f}",third: "{:0,.0f}"}).set_table_styles(styles).render()

```
