Table Enhancer for GitHub

An unofficial extension that makes wide tables easier to read in GitHub Markdown file previews.

Wide GitHub Markdown tables should not turn review into a scrolling exercise. Table Enhancer for GitHub adds compact controls directly above tables on Markdown file preview pages. Keep your place, find the rows that matter, and copy the result—without editing the source file. Stay oriented - Freeze header rows and leading columns while you scroll. - Save Freeze defaults by repository and heading for the tables you revisit. Find what matters - Filter rows by text or regular expression. - Sort by any column, or hide rows and columns you do not need. Shape the view around your task - Fit, wrap, or resize columns for easier reading. - Open one table in full-window Focus mode when you need more space. Take the useful part with you - Copy the visible view as Markdown, CSV, or TSV. Hidden and filtered content stays out of the copy. - Reset temporary changes whenever you want to return to the original view. The extension works only on GitHub Markdown file preview pages (`github.com/.../blob/...`). It does not alter your files or run on issues, pull requests, discussions, or repository landing pages. Freeze defaults are stored locally in Chrome. No user data is collected, transmitted, sold, or shared. Table Enhancer for GitHub is an independent project and is not affiliated with, sponsored by, or endorsed by GitHub.
