## What it is
A Go library for rendering rich text-based tables in ASCII, Unicode, Markdown, HTML, and colorized terminal output. It supports flexible input from CSV, structs, and slices, with styling options like cell merging, alignment, and borders.

## Use cases
- print ascii tables in a go cli tool
- render markdown tables from data
- format query results as a table in the terminal
- generate html tables from go structs
- colorize table output in the terminal
- stream rows into a table in real time

## When to choose
- you need pretty tabular output from a Go CLI or log output
- you want multiple output formats like ASCII, Markdown, or HTML from one library
- you need high-performance table rendering with minimal allocations

## When to avoid
- you need graphical or interactive tables in a web frontend
- you are not working in Go
- you depend on the legacy v0.0.5 API and cannot migrate to the v1 API

## Facets
- artifact type: library
- maturity: stable
- function: developer-tools, cli, templating, data-visualization
- domain: developer-tools, data-visualization
- platform: go, cli, cross-platform
- tags: ascii-table, terminal-output, markdown-tables, html-tables, unicode-tables, table-rendering, command-line
