### Notes
- if the index is 1-dimensional and the name is None we rename to 'index' in order to be able
to format the index.
- For the complete formattings specification see [numbrojs](http://numbrojs.com/format.html)
Args:

int_format (str, optional): The int format string. Defaults to INT_FORMAT.
int_align (str, optional): [description]. Defaults to INT_ALIGN.
float_format (str, optional): [description]. Defaults to FLOAT_FORMAT.
float_align (str, optional): [description]. Defaults to FLOAT_ALIGN.
Returns:
