Streamlit 如何在一行中显示按钮

Question

Hi all I am building a simple web app with streamlit in python. I need to add 3 buttons but they must be on the same line.

Obviously the following code puts them on three different lines

st.button('Button 1')
st.button('Button 2')
st.button('Button 3')

Do you have any tips?

Answer 1

Apparently this should do it

col1, col2, col3 = st.columns([1,1,1])

with col1:
    st.button('1')
with col2:
    st.button('2')
with col3:
    st.button('3')

I had a similar problem - to add an action button to a table. I came to the following approach:

import streamlit as st

        # # Show users table 
        colms = st.columns((1, 2, 2, 1, 1))
        fields = ["№", 'email', 'uid', 'verified', "action"]
        for col, field_name in zip(colms, fields):
            # header
            col.write(field_name)

        for x, email in enumerate(user_table['email']):
            col1, col2, col3, col4, col5 = st.columns((1, 2, 2, 1, 1))
            col1.write(x)  # index
            col2.write(user_table['email'][x])  # email
            col3.write(user_table['uid'][x])  # unique ID
            col4.write(user_table['verified'][x])   # email status
            disable_status = user_table['disabled'][x]  # flexible type of button
            button_type = "Unblock" if disable_status else "Block"
            button_phold = col5.empty()  # create a placeholder
            do_action = button_phold.button(button_type, key=x)
            if do_action:
                 pass # do some action with row's data
                 button_phold.empty()  #  remove button

And it works fine. The object — user_table — is a dictionary very similar to DataFrame, where each key — is a column (ie list in pythonic terms). And here how it looks like (Note “Blocked” — that is the result of action):

I fix it with css styling MOZILLA

import streamlit as st

css_code_tree_button_side_by_side= '''
<style>
#root > div:nth-child(1) > div > div > div > div > section > div > div:nth-child(1) > div > div:nth-child(2) > div{
    display: -webkit-inline-box;
    width: 180px;
}
#root > div:nth-child(1) > div > div > div > div > section > div > div:nth-child(1) > div > div:nth-child(2) > div > div:nth-child(-n+3){
    width: 50px!important;
}
#root > div:nth-child(1) > div > div > div > div > section > div > div:nth-child(1) > div > div:nth-child(2) > div > div:nth-child(-n+3) > div{
    width: 50px!important;
}
#root > div:nth-child(1) > div > div > div > div > section > div > div:nth-child(1) > div > div:nth-child(2) > div > div:nth-child(-n+3) > div > button{
    width: fit-content;
}
</style>
'''


st.markdown(css_code_tree_button_side_by_side, unsafe_allow_html=True)
#I know where this 'box' is so I can play with it
with st.container():
    if st.button('a'):
        pass
    if st.button('b'):
        pass
    if st.button('c'):
        pass
