This template produces a family tree table. The template accepts up to 400 unnamed parameters describing the contents of the table. Each parameter specifies a tile or a box, or a line break.
Tiles are line drawing symbols consisting of horizontal and vertical lines and various corners and crossings thereof. Tiles are specified using single-character symbols that more or less approximate the shape of the tile in appearance. A special case of a tile is the empty tile, specified by a single space character. A table of supported tiles is given below.
A "_" indicates to start a new row.
A box will be formed from any parameter that contains more than two characters. A box is three tiles wide and one tile long, regardless of the string length, so plan the graph accordingly.
