Summary

When using streamlit.dataframe to show an interactive dataframe table, the horizontal scrollbar is always enabled. To show the last digits in the right most column, you always need to scroll. The width parameter of the dataframe only works to decrease the standard width - increase does not work.

Steps to reproduce

Simple code to reproduce:

import pandas as pd
import numpy as np
import streamlit as st

df = pd.DataFrame({
    "A": np.random.randint(0, 10000, 100),
    "B": np.random.randint(0, 10000, 100),
    "C": np.random.random(100) * 10
})

st.dataframe(df)

Behavior

Screenshot of current output below. I expect the horizontal scrollbar to not be there when there is plenty of space for the dataframe to be shown in its entirety.

Is this a regression?

Don't know, first time using streamlit.
