/**
|
|
* General-purpose helper for building fixed-width ASCII/Unicode tables in a TUI.
|
|
*
|
|
* <p>A table is built by adding rows one at a time, then calling {@link #build()}
|
|
* to obtain the fully rendered string. Column width is computed automatically
|
|
* from the widest cell across all rows.
|
|
*
|
|
* <p>Cell widths are measured in terminal columns, not Java {@code char} units:
|
|
* wide characters (emoji, CJK) count as 2 columns each.
|
|
*
|
|
* <p>Example usage:
|
|
* <pre>{@code
|
|
* AsciiTable table = new AsciiTable(BorderStyle.UNICODE, 3);
|
|
* table.addHeader("Name", "🍖", "⭐");
|
|
* table.addRow("Alice", "4", "12");
|
|
* table.addRow("Bob", "2", "8");
|
|
* System.out.println(table.build());
