## Description

Tablewriter is a Go library and tool for generating ASCII and Unicode tables from structured data. It functions as a multi-format table renderer, converting data into layouts for terminal output, Markdown, HTML, and SVG.

The project distinguishes itself through the ability to embed nested tables within cells and merge adjacent cells horizontally or vertically. It also supports ANSI color application for headers, rows, and borders to style terminal user interfaces.

The toolkit provides capabilities for mapping Go structs and slices into rows, loading and converting CSV files via a command-line interface, and streaming table output incrementally. Visual appearance is managed through configurable borders, separators, padding, and alignment settings.
