When to use this skill

How to use this skill

Inputs

• headers (required)
• rows (required)
• maxWidth (default 80)
• maxColWidth (default 20)
• borderStyle (light | minimal, default light)
• overflow (ellipsis | wrap, default ellipsis)
• align (left | right | center, default left)

Outputs (required)

• tableCompact (log-friendly)
• tableReadable (interactive-friendly)
• rules (width/truncation/null/alignment rules)

Steps

1. Compute per-column widths:

   min(maxColWidth, max(contentWidth))

2. Handle overflow:
   • ellipsis: use

     ...

     consistently
   • wrap: wrap within column width while keeping row alignment
3. Output two variants:
   • compact: minimal or fewer separators
   • readable: clearer borders

Script

• scripts/render_table.py

  : render tables from JSON stdin (compact/readable)

Examples

• examples/basic.md

Quality checklist

1. Columns align consistently; each line does not exceed maxWidth
2. Null values are rendered as

   -

3. Copy/paste safe (no trailing spaces)
