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
- Compute per-column widths:
min(maxColWidth, max(contentWidth)) - Handle overflow:
- ellipsis: use ... consistently - wrap: wrap within column width while keeping row alignment
- 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 AwaytableReadable:
+-------+----------+--------+
| Name | Role | Status |
+-------+----------+--------+
| Alice | Engineer | Active |
| Bob | Designer | Away |

Quality checklist
- Columns align consistently; each line does not exceed maxWidth
- Null values are rendered as
- - Copy/paste safe (no trailing spaces)
