Improve further the accessibility of tables on the "Numbers and Dates" page

[AlOneill]

The tables are not bad from an accessibility point of view bu they could be better.

These are the main areas to be considered and addressed:

• complexity of column headings
• lack of row headings

This is initially an issue for one page as described but the conclusions might prove useful for tables on other pages in due course.

Not a priority.

Working off-line for now.

@AlOneill is there any update on this?

Cannot see anything obvious to change: the page will be reviewed by the Accessibility team and the FR documentation committee in due course.
