pandas.io.formats.style.Styler.set_td_classesΒΆ

Styler.set_td_classes(classes)[source]ΒΆ

Add string based CSS class names to data cells that will appear within the Styler HTML result. These classes are added within specified <td> elements.

Parameters
classesDataFrame

DataFrame containing strings that will be translated to CSS classes, mapped by identical column and index values that must exist on the underlying Styler data. None, NaN values, and empty strings will be ignored and not affect the rendered HTML.

Returns
selfStyler

Examples

>>> df = pd.DataFrame(data=[[1, 2, 3], [4, 5, 6]], columns=["A", "B", "C"])
>>> classes = pd.DataFrame([
...     ["min-val red", "", "blue"],
...     ["red", None, "blue max-val"]
... ], index=df.index, columns=df.columns)
>>> df.style.set_td_classes(classes)

Using MultiIndex columns and a classes DataFrame as a subset of the underlying,

>>> df = pd.DataFrame([[1,2],[3,4]], index=["a", "b"],
...     columns=[["level0", "level0"], ["level1a", "level1b"]])
>>> classes = pd.DataFrame(["min-val"], index=["a"],
...     columns=[["level0"],["level1a"]])
>>> df.style.set_td_classes(classes)

Form of the output with new additional css classes,

>>> df = pd.DataFrame([[1]])
>>> css = pd.DataFrame(["other-class"])
>>> s = Styler(df, uuid="_", cell_ids=False).set_td_classes(css)
>>> s.hide_index().render()
