Anatomy of a table
The figure below shows all spacing characteristics of a table.
The outer rectangle (using +, -, and | characters) marks the most outer part of a table.
This is followed by top, bottom, left, and right frame margins.
The next rectangle (using the UTF-8 double line characters) shows an example grid. Inside the grid 4 rows with different column spans are shown.
The next figure shows the anatomy of a single table cell. The core is the text in the middle. Top and bottom padding can be added (whole lines before and after the text). Left and right padding can be added to the text.
