pandas.formats.style.Styler.apply

Styler.apply(func, axis=0, subset=None, **kwargs)

Apply a function column-wise, row-wise, or table-wase, updating the HTML representation with the result.

New in version 0.17.1.

Parameters:	func: function axis: int, str or None apply to each column (axis=0 or 'index') or to each row (axis=1 or 'columns') or to the entire DataFrame at once with axis=None. subset: IndexSlice a valid indexer to limit data to before applying the function. Consider using a pandas.IndexSlice kwargs: dict pass along to func
Returns:	self : Styler

Notes

This is similar to DataFrame.apply, except that axis=None applies the function to the entire DataFrame at once, rather than column-wise or row-wise.
