When to use this skill

CRITICAL TRIGGER RULE

  • Use this skill ONLY when the user explicitly mentions the exact skill name: 
    ascii-table-renderer
    .

Trigger phrases include:

  • "ascii-table-renderer"
  • "use ascii-table-renderer"
  • "用 ascii-table-renderer 把列表打印成表格"
  • "使用 ascii-table-renderer 生成 ASCII 表格（对齐/列宽）"

Boundary

  • Do not fetch data (DB/API). Only render and format output.
  • Default borders are ASCII-only: 
    + - |
    .
  • Out of scope: merged cells, multi-row headers, complex spanning layouts.

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)

Inline Example

Input: 

headers=["Name", "Role", "Status"]
, 
rows=[["Alice", "Engineer", "Active"], ["Bob", "Designer", "Away"]]

tableCompact:

Name   Role      Status
Alice  Engineer  Active
Bob    Designer  Away

tableReadable:

+-------+----------+--------+
| Name  | Role     | Status |
+-------+----------+--------+
| Alice | Engineer | Active |
| Bob   | Designer | Away   |
+-------+----------+--------+

  • 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)
