Streamlit 1.60 adds tab height control, pixel gaps, and hidden CSV export

andfanilo · x · 2026-07-26

Streamlit 1.60.0 is out, and the release focuses on layout and UX controls for app builders.

The screenshots highlight three notable changes:

you can hide the CSV export button on dataframe and chart table views via client.disableDataExport or st.setoption("client.disableDataExport", True);
st.tabs() now supports fixed heights or stretching to the parent container;
st.columns() accepts a literal pixel gap, while still supporting predefined sizes like small and xlarge.

The post also notes that hiding export is only a UI convenience — data can still be recovered through browser devtools or network inspection.
