DSL and builder API for constructing customizable text-rendered tables with features like borders, padding, individual cell styling, header/footer sections, row/column spans, and text alignment.
A Kotlin DSL and Java/Kotlin builder API for constructing HTML-like tables which can be rendered to text.
Features:
DSL:
table {
row("Hello", "World")
row("Hola", "Mundo")
}
HelloWorld
Hola Mundo
Very underwhelming! Picnic tables start completely unstyled by design.
