Use, Styler.applymap(func) for elementwise styles, Styler.apply(func, axis=0) for columnwise styles, Styler.apply(func, axis=1) for rowwise styles, Styler.apply(func, axis=None) for tablewise styles. Both Styler.apply, and Styler.applymap accept a subset keyword. Styler also provides a few other options for styles that don’t depend on the data. Below are data formats that DataFrame supports, which means if your data is in any of the below forms, you can use pandas to load that data format and even write into a particular format.

If table_styles is given as a dictionary each key should be a specified column or index value and this will map to specific class CSS selectors of the given column or row. The value passed to subset behaves similar to slicing a DataFrame. 30. Use the Styler constructor when building many styled DataFrames that should all share the same properties. Or pass in a callable (or dictionary of callables) for more flexible handling. Pass your style functions into one of the following methods: Both of those methods take a function (and some other keyword arguments) and applies your function to the DataFrame in a certain way. There’s also .highlight_min and .highlight_max. Now we can use that custom styler. © Copyright 2008-2021, the pandas development team.

If your style function uses a subset or axis keyword argument, consider wrapping your function in a functools.partial, partialing out that keyword. Syntax. You can create “heatmaps” with the background_gradient method. With that in mind, we hope that DataFrame.style accomplishes two goals, Provide an API that is pleasing to use interactively and is “good enough” for many tasks, Provide the foundations for dedicated libraries to build on. Notice that the output shape of highlight_max matches the input shape, an array with len(s) items. Notice also that our function returned a string containing the CSS attribute and value, separated by a colon just like in a
