What's Changed

Improvements (better tracebacks!) and bug fixes, as well as a new feature: tables now support columnwise formatting!

python
format_mapping is a dict keyed by column names,
with values as formatting functions or strings
def format_name(name):
return name.upper()


table = mo.ui.table(
data=[
{"first_name": "Michael", "last_name": "Scott", "age": 45},
{"first_name": "Dwight", "last_name": "Schrute", "age": 40},
],
format_mapping={
"first_name": format_name, Use callable to format first names
"age": "{:.1f}".format, Use string format for age
},
label="Format Mapping",
)

What's Changed

Highlights

**Terminal panel 💻**. The marimo editor now includes a terminal that lets you run shell commands in a pseudo-terminal, without having to return to your actual terminal. This feature is currently supported on macOS and Linux.

**TOC outlines! 📑** We know notebooks can get long. That's why we now automatically include a floating TOC outline in preview/run mode, making it easy to get a birds-eye view of a notebook and to navigate to specific sections.


**Pan and zoom on `mo.ui.altair_chart` 🖱** Hold `ctrl/cmd` and click to pan and zoom on your Altair charts.

**Let me Google that for you.** Tracebacks now include a "search with Google" button.

**Let me fix that for you!** If you have AI Assist enabled, tracebacks include a `Fix with AI` button that will try to automatically fix your bug.

What's Changed

Highlights

**✍ Scratchpad panel.** Version 0.7.9 ships with a new panel: the scratchpad. The scratchpad panel lets you type arbitrary Python code, free from the restrictions of marimo's constraints. Scratchpad code doesn't get saved into your notebook; instead, it's an exploratory REPL for quick and dirty analyses.


**Collapsible markdown headings.** You can now collapse sections of your notebooks, based on markdown headings. For example, collapse all cells under an `H2` heading. This makes it much easier to work with long notebooks.
