I am coding these tables in HTML and am required to code for accessibility. Financial tables typically show negative numbers in parentheses. Is that considered 508/WCAG compliant? Or should negative numbers be shown as -$100.00?
The title of the table is "Tax Revenue in Millions of Dollars" and the table headings are years, and then percent change. The table itself doesn't mention dollars. Do I need to put dollar signs before the numbers?
