Ability to set dataframe column width

See original GitHub issue

See: https://discuss.streamlit.io/t/is-there-a-way-to-specify-column-width-for-dataframe-table/333

st.dataframe tries to be smart about column sizes, but often misses the mark — so users end up with dataframes that have truncated/ellipsized values.

On Jupyter, you can apply a width-modifying Styler to a dataframe like this: https://stackoverflow.com/a/39680725

We should add support for something like that in Streamlit.

Any timeline for this (much wanted) feature? Thanks!

The new st.dataframe enforces column width based on its contents while truncating the header, which leads to “squeezing” of the rendered dataframe and unreadability of the header in some cases. Manual column resizing can partially solve this problem (except for the rightmost column), but it is inconvenient for the user when the number of columns is high. Previous UI allowed the dataframe to use all available screen width (in wide layout mode), didn’t truncate the header and displayed full column header text in a popup window on hover.

It would be nice to have access to “old-style” st.dataframe UI or the option to prevent header truncating in future updates.
