Great Tables and StreamLit

February 1, 2025

Great Tables is a Python package that can help display tables in a visually appealing way. It does appear to work in StreamLit according to this post. According to edsaac, it can be done by exporting the GT object as html and passing it to st.html works OK. Below is the example edsaac provided:

from great_tables import GT, html
from great_tables.data import sza
import polars as pl
import streamlit as st

st.title(
    ":balloon: Displaying a Great Table",
    help="Check `great_tables` [documentation](https://posit-dev.github.io/great-tables/reference/GT.html#great_tables.GT.as_raw_html)",
)

with st.echo(code_location="below"):
    ## Example from https://posit-dev.github.io/great-tables/examples/
    sza_pivot = (
        pl.from_pandas(sza)
        .filter((pl.col("latitude") == "20") & (pl.col("tst") <= "1200"))
        .select(pl.col("*").exclude("latitude"))
        .drop_nulls()
        .pivot(values="sza", index="month", on="tst", sort_columns=True)
    )

    table = (
        GT(sza_pivot, rowname_col="month")
        .data_color(
            domain=[90, 0],
            palette=["rebeccapurple", "white", "orange"],
            na_color="white",
        )
        .tab_header(
            title="Solar Zenith Angles from 05:30 to 12:00",
            subtitle=html("Average monthly values at latitude of 20&deg;N."),
        )
        .sub_missing(missing_text="")
        .as_raw_html()
    )

    st.html(table)
