julia-prettytables - SKILL.md Agent Skill

name: julia-prettytables description: Render Julia tables with PrettyTables.jl in text, markdown, and HTML backends, including table sections (titles, labels, summary rows, footnotes), formatters, highlighters, and backend-specific styling/format options. Use this skill when displaying matrix/table data for terminal output, markdown reports, or HTML pages.

Julia PrettyTables

Use PrettyTables.jl to render tabular data consistently across text, markdown, and HTML outputs.

Core Rendering Flow

using PrettyTables

pretty_table(data)  # default text backend
md = pretty_table(String, data; backend=:markdown)
html = pretty_table(String, data; backend=:html, stand_alone=true)

Use String output when the table must be embedded in logs, markdown files, or generated HTML.

Configure Table Sections

Use section-related keywords for report-style output:

title, subtitle
column_labels, row_labels, show_row_number_column, row_group_labels
summary_rows, summary_row_labels
footnotes, source_notes
merge_column_label_cells

For alignment and display behavior:

alignment, column_label_alignment, other section-specific alignment options
maximum_number_of_rows, maximum_number_of_columns, vertical_crop_mode
renderer, compact_printing, limit_printing

Format and Highlight Data

Use formatters to transform displayed cell text.
Use backend-specific highlighters:
- TextHighlighter
- MarkdownHighlighter
- HtmlHighlighter

Apply formatter logic first in design, then add highlighters for visual emphasis.

Backend-Specific Controls

Text (backend=:text): table_format::TextTableFormat, style::TextTableStyle, line wrapping/cropping controls.
Markdown (backend=:markdown): allow_markdown_in_cells, line_breaks, table_format::MarkdownTableFormat.
HTML (backend=:html): allow_html_in_cells, stand_alone, minify, wrap_table_in_div, table_format::HtmlTableFormat, style::HtmlTableStyle.

Prefer markdown backend for docs/README and HTML backend for web/report export.
