具有两个标题行的固定宽度表格。

第一个标题行定义列名，第二个标题行隐式定义列位置。

实例：

# Typical case with column extent defined by ---- under column names.

 col1    col2         <== header_start = 0
-----  ------------   <== position_line = 1, position_char = "-"
  1     bee flies     <== data_start = 2
  2     fish swims

# Pretty-printed table

+------+------------+
| Col1 |   Col2     |
+------+------------+
|  1.2 | "hello"    |
|  2.4 | there world|
+------+------------+
