⚠️ gt-extras is currently in development, expect breaking changes.

What is gt-extras?

A collection of additional helper functions for creating beautiful tables with the great-tables package in Python.

The functions in gt-extras are designed to make it easier to add plots, icons, color gradients, and other enhancements to your tables. We wrap up common patterns and boilerplate so you can focus on your data and presentation. It is based on the R package gtExtras, which was designed with a similar goal in mind.

Installation

Install the latest release from PyPI: pip install gt-extras

Example Usage

from great_tables import GT
from great_tables.data import gtcars
import gt_extras as gte

gtcars_mini = gtcars.iloc[5:15].copy().reset_index(drop=True)
gtcars_mini["efficiency"] = gtcars_mini["mpg_c"] / gtcars_mini["hp"] * 100

(
    # Start with a standard GT 
    GT(gtcars_mini, rowname_col="model")
    .tab_stubhead(label="Vehicle")
    .cols_hide(["drivetrain", "hp_rpm", "trq_rpm", "trim", "bdy_style", "msrp", "trsmn", "ctry_origin"])
    .cols_align("center")
    .tab_header(title="Car Performance Review", subtitle="Using gt-extras functionality")

    # Add gt-extras features using gt.pipe()
    .pipe(gte.gt_color_box, columns=["hp", "trq"], palette=["lightblue", "darkblue"])
    .pipe(gte.gt_plt_dot, category_col="mfr", data_col="efficiency", domain=[0, 0])
    .pipe(gte.gt_plt_bar, columns=["mpg_c", "mpg_h"])
    .pipe(gte.gt_fa_rating, columns="efficiency")
    .pipe(gte.gt_hulk_col_numeric, columns="year", palette="viridis")
    .pipe(gte.gt_theme_538)
