philiprehberger-text-table

Render data as clean ASCII/Unicode tables in the terminal with zero configuration.

Installation

pip install philiprehberger-text-table

Usage

from philiprehberger_text_table import table

headers = ["Name", "Age", "City"]
rows = [
    ["Alice", 30, "New York"],
    ["Bob", 25, "London"],
    ["Charlie", 35, "Tokyo"],
]

print(table(headers, rows))

Output:

┌─────────┬─────┬──────────┐
│ Name    │ Age │ City     │
├─────────┼─────┼──────────┤
│ Alice   │  30 │ New York │
│ Bob     │  25 │ London   │
│ Charlie │  35 │ Tokyo    │
└─────────┴─────┴──────────┘

From dictionaries

from philiprehberger_text_table import from_dicts

data = [
    {"name": "Alice", "score": 95},
    {"name": "Bob", "score": 87},
]

print(from_dicts(data))

From CSV

from philiprehberger_text_table import from_csv

print(from_csv("data.csv"))

Styles

# ASCII style
print(table(headers, rows, style="ascii"))

# Markdown style
print(table(headers, rows, style="markdown"))

# Minimal style (no borders)
print(table(headers, rows, style="minimal"))

# Compact style (no outer borders)
print(table(headers, rows, style="compact"))

Column alignment

# Override auto-detection for all columns
print(table(headers, rows, align="center"))

# Per-column alignment
print(table(headers, rows, align=["left", "center", "right"]))

From CSV string

from philiprehberger_text_table import from_csv_string

csv_data = "Name,Age\nAlice,30\nBob,25"
print(from_csv_string(csv_data))

Truncation

print(table(headers, rows, max_width=10))

Round-tripping CSV

from philiprehberger_text_table import to_csv, from_csv

csv_text = to_csv(
    [["Alice", 30], ["Bob", 25]],
    headers=["Name", "Age"],
    file="people.csv",  # optional — also writes to disk
)
print(csv_text)
# Name,Age
# Alice,30
# Bob,25

# Re-read and render
print(from_csv("people.csv"))

Computing column widths

from philiprehberger_text_table import column_widths

widths = column_widths(["name", "count"], [["alice", 100], ["bob", 5]])
# [5, 5]  — max of header and cell str-lengths per column

API

Function	Description
table(headers, rows, *, style="unicode", max_width=None, align=None)	Render a table from headers and row data
from_dicts(data, *, style="unicode", max_width=None, align=None)	Render a table from a list of dictionaries
from_csv(path, *, style="unicode", max_width=None, align=None)	Read a CSV file and render as a table
from_csv_string(text, *, style="unicode", max_width=None, align=None)	Render a table from CSV string content
to_csv(rows, *, headers=None, file=None)	Render rows back to a CSV string (round-trips with from_csv); optionally writes to a file
column_widths(headers, rows)	Return the per-column widths the renderer would compute

Styles: "unicode", "ascii", "markdown", "minimal", "compact"

Alignments: "left", "right", "center" (default: auto-detect, numeric columns right-aligned)
