Maintaining the display of a dataframe

Hello everybody !
I have a problem, I use buttons to make some computing and displaying dataframes, I press the first button to display my first dataframe and when I press the second button, my second dataframe is shown but my first disappears. I want to maintain the display of my first dataframe (and all those before)…
A code example :

import streamlit as st
import pandas as pd

st.subheader("Test")

df_first = pd.DataFrame({"col1": [1, 2, 3, 1, 2, 3], "col2": [4, 5, 6, 4, 5, 6]})
df_second = pd.DataFrame({"col1": [100, 200, 300], "col2": ["www.google.com", "www.facebook.com", "www.youtube.com"]})

button_first = st.button("Display first")
if button_first :
    st.write(df_first)

button_second = st.button("Display second")
if button_second:
    st.write(df_second) 

Anybody know how to proceed ?

@nvk - display the tables using button on_click callbacks. A button’s True state is only valid at the time it is clicked, then it immediately returns to False when Streamlit reruns. Or you can use st.checkbox instead.
