pubtab

Language: English | 中文

Convert Excel tables to publication-ready LaTeX (and back) with stable roundtrip behavior.

Highlights

• Roundtrip Consistency — Designed for tex -> xlsx -> tex workflows with minimal structural drift.
• Multiple TeX Backends — Supports both classic tabular export and tabularray / tblr output.
• All-Sheets by Default — xlsx2tex exports every sheet as *_sheetNN.tex when --sheet is not set.
• Style Fidelity — Preserves merged cells, colors, rich text, rotation, and common table semantics.
• Publication Preview — Generate PNG/PDF directly from .tex via one CLI entry.
• Overleaf-Ready Output — Generated .tex starts with commented \usepackage{...} hints.

Recent News

• 2026-03-18: tabularray backend support and README refresh — added tabularray as an alternative TeX backend for xlsx2tex, updated theme/backend resolution so three_line can be used consistently across render and preview, replaced placeholder usage paths with real repo examples under examples/, documented GitHub dev installation, and removed the repository test directory from the tracked tree.
• 2026-03-06: Preview dependency recovery and resizebox controls — improved TinyTeX / missing-package recovery in preview, and added resizebox-related CLI switches for more reliable wide-table export.
• 2026-03-05: PyPI-safe README cleanup and release prep — switched README links to PyPI-safe forms and prepared the 1.0.1 release workflow.

Examples

Showcase

Example A: Excel -> LaTeX

pubtab xlsx2tex ./examples/table4.xlsx -o ./out/table4.tex

Output file:

• ./out/table4.tex

Example B: LaTeX -> Excel (roundtrip from the generated sample)

pubtab tex2xlsx ./out/table4.tex -o ./out/table4_roundtrip.xlsx

Example C: LaTeX -> PNG / PDF preview

pubtab preview ./out/table4.tex -o ./out/table4.png --dpi 300
pubtab preview ./out/table4.tex --format pdf -o ./out/table4.pdf

Example D: Excel -> tabularray (tblr)

pubtab xlsx2tex ./examples/table4.xlsx -o ./out/table4_tblr.tex \
  --theme three_line \
  --latex-backend tabularray

# Preview the generated tabularray tex file
pubtab preview ./out/table4_tblr.tex -o ./out/table4_tblr.png \
  --theme three_line --latex-backend tabularray --dpi 300

Generated .tex header includes package hints (comments only):

% Theme package hints for this table (add in your preamble):
% \usepackage{booktabs}
% \usepackage{multirow}
% \usepackage[table]{xcolor}

Quick Start

# Preview (.png by default)
pubtab.preview("table.tex", dpi=300)

# Native batch pipeline (directory input)
pubtab.tex_to_excel("tables_tex", "out/xlsx")

# Export a specific sheet only
pubtab xlsx2tex report.xlsx -o out/report.tex --sheet "Main"

# Two-column table + preview
pubtab xlsx2tex report.xlsx -o out/report.tex --span-columns --preview --dpi 300

# Export with the tabularray backend
pubtab xlsx2tex report.xlsx -o out/report_tblr.tex --latex-backend tabularray

# Preview a generated tabularray table
pubtab preview out/report_tblr.tex -o out/report_tblr.png --theme three_line --latex-backend tabularray --dpi 300

Features by Workflow

1) Excel -> LaTeX

• Reads .xlsx (openpyxl) and .xls (xlrd), then renders via Jinja2 themes.
• Preserves rich formatting: merged cells, colors, bold/italic/underline, rotation, diagbox, and multi-line cells.
• Applies table-level logic: header rule generation, section/group separators, and trailing-empty-column trimming.
• Supports all-sheet export by default and deterministic *_sheetNN file naming.

2) LaTeX -> Excel

• Parses multiple tables from one .tex file and writes each table to separate worksheet(s).
• Handles commands including \multicolumn, \multirow, \textcolor, \cellcolor, \rowcolor, \diagbox, and \rotatebox.
• Expands macros (\newcommand/\renewcommand) and resolves \definecolor variants.
• Improves robustness for row/cell splitting around escaped separators and nested wrappers.

3) Preview Pipeline

• pubtab preview compiles .tex to PNG/PDF using available local LaTeX tooling.
• If system pdflatex is unavailable, TinyTeX auto-install can bootstrap compilation.
• On missing .sty errors, pubtab can parse the missing package, run tlmgr install <package>, and retry compile automatically.
• TinyTeX download uses cert-friendly SSL handling and now provides actionable hints for certificate failures.
• PNG conversion works out of the box after pip install pubtab (bundled pdf2image + PyMuPDF backends).

Configuration

Use a YAML file to define repeatable defaults. CLI arguments always take precedence over config values.

theme: three_line
latex_backend: tabularray
caption: "Experimental Results"
label: "tab:results"
header_rows: 2
sheet: null
span_columns: false
position: htbp
font_size: footnotesize
resizebox: null
col_spec: null
header_sep: null
preview: false
dpi: 300
spacing:
  tabcolsep: "4pt"
  arraystretch: "1.2"
group_separators: [3, 6]

pubtab xlsx2tex table.xlsx -o output.tex -c config.yaml

Recommended backend pairing:

• theme: three_line + latex_backend: tabular -> classic tabular
• theme: three_line + latex_backend: tabularray -> three_line style rendered through the tabularray backend

Theme System

pubtab uses a Jinja2-based theme system. The built-in three_line theme targets academic booktabs-style tables and can be rendered through either the classic tabular backend or the tabularray backend.

Custom theme layout:

my_theme/
├── config.yaml    # packages, spacing, font_size, caption_position
└── template.tex   # Jinja2 template
