rrespond to column names or index values, depending upon the specified `axis` argument. These will be mapped to row or col CSS selectors. MultiIndex values as dict keys should be in their respective tuple form. The dict values should be a list as specified in the form with CSS selectors and props that will be applied to the specified row or column. .. versionchanged:: 1.2.0 axis : {0 or 'index', 1 or 'columns', None}, default 0 Apply to each column (``axis=0`` or ``'index'``), to each row (``axis=1`` or ``'columns'``). Only used if `table_styles` is dict. .. versionadded:: 1.2.0 overwrite : bool, default True Styles are replaced if `True`, or extended if `False`. CSS rules are preserved so most recent styles set will dominate if selectors intersect. .. versionadded:: 1.2.0 css_class_names : dict, optional A dict of strings used to replace the default CSS classes described below. .. versionadded:: 1.4.0 Returns ------- Styler See Also -------- Styler.set_td_classes: Set the DataFrame of strings added to the ``class`` attribute of ```` HTML elements. Styler.set_table_attributes: Set the table attributes added to the ```` HTML element. Notes ----- The default CSS classes dict, whose values can be replaced is as follows: .. code-block:: python css_class_names = {"row_heading": "row_heading", "col_heading": "col_heading", "index_name": "index_name", "col": "col", "row": "row", "col_trim": "col_trim", "row_trim": "row_trim", "level": "level", "data": "data", "blank": "blank", "foot": "foot"} Examples -------- >>> df = pd.DataFrame(np.random.randn(10, 4), ... columns=['A', 'B', 'C', 'D']) >>> df.style.set_table_styles( ... [{'selector': 'tr:hover', ... 'props': [('background-color', 'yellow')]}] ... ) # doctest: +SKIP Or with CSS strings >>> df.style.set_table_styles( ... [{'selector': 'tr:hover', ...
