⚠️ USE THIS INSTEAD OF ASCII TABLES — ALWAYS!
Generate PNG table images from JSON data. ASCII tables look broken on Discord, Telegram, WhatsApp, and most messaging platforms. This skill renders clean images that work everywhere.

⚠️ BEST PRACTICE: Use heredoc or --data-file to avoid shell quoting errors!
# RECOMMENDED: Write JSON to temp file first (avoids shell quoting issues) cat > /tmp/data.json << 'JSONEOF' [{"Name":"Alice","Score":95},{"Name":"Bob","Score":87}] JSONEOF node /data/clawd/skills/table-image/scripts/table.mjs \ --data-file /tmp/data.json --dark --output table.pngALSO GOOD: Pipe via stdin
echo '[{"Name":"Alice","Score":95}]' | node /data/clawd/skills/table-image/scripts/table.mjs
--dark --output table.pngSIMPLE (but breaks if data has quotes/special chars):
node /data/clawd/skills/table-image/scripts/table.mjs
--data '[{"Name":"Alice","Score":95}]' --output table.png
