Hadley Wickham in a white t-shirt and jeans sits on a light-colored couch across from Michael Chow, wearing a dark green shirt and pants, who is seated on an orange pouf. Between them is a white coffee table with books. In the background, there's a dark bar with shelves displaying numerous bottles, a wood-paneled wall, and a black, modern fireplace. Text overlay reads "Hadley Wickham CHIEF SCIENTIST, POSIT".

New post! Great Tables: Becoming the Polars .style property

When you use Polars `DataFrame.style` it returns a Great Tables object. This is a bit cheesy, but I look back on all the pieces the open source community chipped in to make this happen 🥲.

Python code using Polars and great_tables libraries to create a DataFrame with two columns and apply a blue background style to rows where column 'a' contains null values. The code is followed by an image showing the resulting styled table. Here is the Python code: ``` import polars as pl from great_tables import loc, style ( pl.DataFrame({"a": [1, None], "b": [3, 4]}) .style .tab_style( style.fill("aliceblue"), loc.body(rows=pl.col("a").is_null()) ) ) ```

I'm looking to contribute to tools for analyzing public transit data in 2025--and would love to hear from folks!

A table made by Great Tables, showing names of Paris Metro stations. There is a column called lines, which shows each line number at that station. And a column called passengers, with the number of passengers with the total number of station entries in 2021.
