🚀 SuperTables — Explore, Filter & Export Any Table on Any Page

SuperTables turns the raw tables on any website into an interactive workspace — filter rows, sort columns, chart data, and export exactly what you need, without ever leaving the page or opening a spreadsheet. Works on HTML tables, ARIA grids, and complex visual layouts alike. Everything runs entirely in your browser; no data ever leaves your device.

✨ CORE FEATURES
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🔍 Smart Table Detection
• Detects HTML tables, ARIA grids/treegrids, shadow-DOM tables, and visual "table-like" layouts
• Cycle through every detected region with Prev / Next — each is highlighted on the page
• Picker mode: click a crosshair directly onto any table-like region to grab it instantly
• Live row and column count updates as you navigate or filter
• Automatically hides repeated header rows in paginated single-page tables so duplicates never clutter your view

🧪 Powerful Filtering — Right on the Page
A filter row drops in directly under the table header. Filter every column independently, in real time:

Numeric & range expressions
<5 >=100 =42 BW(1,10)

Set & substring filters
IN(a,b,c) NOT IN(x,y) LIKE(foo,bar)

Formula filters (new!)
=ISNUMERIC(True/False) — keep only numeric / non-numeric cells
=ISBLANK(True/False) / =ISEMPTY(True/False) — empty or non-empty cells
=ISTEXT(True/False) — text-only or non-text cells
=CONTAINS(text) / =STARTSWITH(text) / =ENDSWITH(text) — string tests
LEN>5 LEN<=10 — filter by cell text length
!expression — negate any filter above

Pattern matching
Anything else is treated as a case-insensitive regular expression

• Click the ℹ info icon in the filter row for an always-handy syntax reference
• After filtering, the page smoothly scrolls the filter row back into view

📌 Pinned Filters — Auto-Restore on Every Visit
• Click Pin Filters on any table to save the current filter set for that URL
• Filters are re-applied automatically the next time you visit the page
• If you adjust filters on a pinned page, a 🔄 Update Pin button appears — one click saves the new filters as the pinned set
• Manage all pinned pages from the Saved Filters tab in the popup

💾 Stored Tables — Your Personal Table Archive
• Save any table view (with its filters, sort, and hidden columns) inside the extension
• Reopen the source URL from the stored-tables list and the saved view is automatically restored
• Open stored tables in a standalone viewer tab — even works on restricted pages
• Rename, copy, export, or delete any stored entry
• Back up all stored tables and pinned filters to a single JSON file; restore them anytime
• Search and sort the stored-tables list

📊 Instant Data Insights
• Column stats: sum, average, median, mode — computed on visible (filtered) rows
• Column charts: compare up to 4 columns side-by-side with Bar, Line, or Area charts
• Inspect any individual row in a full-detail modal

🧘 Zen Mode — Full-Screen Table Workspace
• Opens the table in a distraction-free overlay right inside the page
• Filter (with the full formula engine above), sort, hide columns, and inspect rows
• Inline cell editing — edit any cell value and export the modified data
• Drag column borders to resize; click headers to sort

📤 Flexible Export
• Export to CSV, Markdown table, or JSON
• Copy to clipboard (tab-delimited — pastes directly into Excel or Google Sheets)
• Pick exactly which columns to include
• Choose filtered rows only, or the full table
