5.3 Tables

Para 1 add "." at end.

Para 2 ...browse in one dimension, i.e. for whom tables are rendered serially.
_The content of any table cell that visually wraps onto more than one line
can be a problem. If only one cell has content that wraps, there is less
problem if it is in the last column.

5.3.1. Add paragraph such as:

_Describe in the table summary attribute value the table structure
