If you’re just looking for a generic example, here’s one:

import pandas as pd
import streamlit as st

data = [
    {
        "name": "Bob",
        "age": 13,
        "grades": {
            "Math": 100,
            "English": 90,
            "Science": 80,
        },
    },
    {
        "name": "Alice",
        "age": 12,
        "grades": {
            "Math": 90,
            "English": 80,
            "Science": 70,
        },
    },
    {
        "name": "Charlie",
        "age": 11,
        "grades": {
            "Math": 80,
            "English": 70,
            "Science": 60,
        },
    },
]

df = pd.DataFrame(data)

overall_data = df[["name", "age"]]

selected_row = st.dataframe(
    overall_data, on_select="rerun", selection_mode="single-row"
)

try:
    row_id = selected_row["selection"]["rows"][0]
except IndexError:
    st.write("Select a row above to see more detail")
    st.stop()

row = data[row_id]

grades = row["grades"]

st.write(f"Grades for {row['name']}")
st.dataframe(grades, hide_index=True)
