tablescope
tablescope is a Marimo-oriented lazy table viewer. It accepts a dataframe-like
object that Narwhals can normalize, keeps sort and aggregation work pushed down
to the underlying engine, and renders a Solid + TanStack data grid via
anywidget.
Install
pip install tablescope
Status
This is a first pass focused on:
- lazy row paging with backend pushdown
- arbitrary fraction jumps through the dataset
- per-column profile stats
- value counts for enum-like columns
- keyboard navigation in the grid
Usage
import marimo as mo
import polars as pl
import tablescope
lf = pl.scan_parquet("data.parquet")
viewer = tablescope.view(lf, page_size=100)
